Stereospecific Conversion of Boronic Esters into Enones using Methoxyallene: Application in the Total Synthesis of 10-Deoxymethynolide. Angew Chem Int Ed Engl 2023; 62:e202312054.

Abstract
Enones are widely utilized linchpin functional groups in chemical synthesis and molecular biology. We herein report the direct conversion of boronic esters into enones using commercially available methoxyallene as a three-carbon building block. Following boronate complex formation by reaction of the boronic ester with lithiated-methoxyallene, protonation triggers a stereospecific 1,2-migration before oxidation generates the enone. The protocol shows broad substrate scope and complete enantiospecificity is observed with chiral migrating groups. In addition, various electrophiles could be used to induce 1,2-migration and give a much broader range of α-functionalized enones. Finally, the methodology was applied to a 14-step synthesis of the enone-containing polyketide 10-deoxymethynolide.

Abstract
We report a 13-step enantioselective and stereoselective total synthesis of (-)-peyssonnoside A, a unique diterpene glucoside with a rare and highly congested pentasubstituted cyclopropane and promising antimicrobial activity. Among the 10 steps to synthesize (-)-peyssonnosol, the aglycone of (-)-peyssonnoside A, eight transition-metal-catalyzed transformations enabled the construction of all new C-C bonds and stereocenters without involving any protecting groups. Notably, a palladium-catalyzed dearomative cyclization was used to build the C-6 spiro all-carbon quaternary center, and a counterintuitive hydrogen atom transfer (HAT)-initiated reductive olefin cross-coupling was realized to forge the pentasubstituted cyclopropane ring with excellent stereoselectivity.

Abstract
Peyssonnoside A is a marine-derived sulfated diterpenoid glucoside with a unique 5/6/3/6 tetracyclic skeleton with a highly substituted cyclopropane ring deeply embedded into the structure. Herein, we report the first total synthesis of this natural product in a concise, efficient, scalable, and highly diastereoselective fashion. The aglucone peyssonnosol was synthesized in 21% overall yield after 15 steps, featuring a Simmons-Smith cyclopropanation and Mukaiyama hydration, fully controlled by the spatial structure of the substrates.

Abstract
The stereoselective cyanoalkylation of electron-deficient olefins with potassium cyanide and alkyl halides was developed based on the utilization of modular chiral 1,2,3-triazolium salts featuring a hydrogen bond-donor ability as catalysts. The reaction involving multiple carbon-carbon bond formations proceeds via the enantioselective conjugate addition of a cyanide ion and the consecutive catalyst-controlled diastereoselective alkylation of intermediary chiral triazolium enolates. Control experiments revealed that the use of a properly tuned chiral triazolium ion as a catalyst and the presence of the cyano functionality in the intermediary enolate are of crucial importance for achieving high levels of acyclic absolute and relative stereocontrol.

Abstract
Pactamycin and jogyamycin are aminocyclopentitol natural products, where each core carbon bears a stereodefined alcohol or amine moiety. Their structural complexity, coupled with the diversity of functional groups coexisting in a condensed space, make them fascinating synthetic targets in their own right. Pactamycin and its derivatives bind to the 30S ribosomal subunit and display activity against parasites responsible for drug-resistant malaria and African sleeping sickness; however, efforts to develop their therapeutic potential have been hampered by their cellular toxicity. Interestingly, bioengineered analogues display differences in selectivity and toxicity towards mammalian cells, spurring efforts to develop flexible strategies to thoroughly probe structure-activity relationships (SAR), particularly in analogues lacking the C7 hydroxyl group of pactamycin. This review compares and contrasts approaches towards pactamycin and jogyamycin, including two successful total syntheses of the former. The implications of each route for preparing analogues to inform SAR and lead to compounds with increased selectivity for binding malarial over human ribosomes are briefly discussed.

Abstract
Jogyamycin is a member of the aminocyclopentitol class of natural products that exhibits significant antiprotozoal activities against diseases that include African sleeping sickness and malaria. Herein, we report a route to the core of this natural product via an underutilized Ichikawa rearrangement as a key step. This route efficiently forms the cyclopentane ring from simple and easily accessible starting materials and rapidly installs the C1/C4/C5 polar functional groups. In addition, this strategy shows excellent potential for the preparation of analogues of jogyamycin to study how structural changes impact the selectivity in binding to the ribosome.

Abstract
Development of enantioselective synthesis of precursor en route to paxilline indoloterpenoids is described. Evaluation of 25 diphosphine-based ligands has led to identification of JosiPhos derivative that allows for asymmetric conjugate addition of homoprenyl Grignard reagent to 2-methylcyclopent-2-en-1-one in excellent yield and with appreciable levels of enantioinduction. Application to the conjugate addition of other Grignard reagents is demonstrated.

Abstract
A catalytic enantioselective conjugate addition with commercially available allenylboronic acid pinacol ester as nucleophile promoted by a chiral copper complex of N-heterocyclic carbene (NHC) is disclosed. This process constitutes an unprecedented instance of the conjugate addition that introduces an allenyl group into α,β-unsaturated carbonyl compounds, affording products that are otherwise difficult to access in up to 92% yield, >98% allenyl addition selectivity and 96:4 enantiomeric ratio. DFT calculations were performed to elucidate the origins of enantioselectivity.

Abstract
A total synthesis of the cytotoxic terpenoid hortonone C was accomplished and its absolute stereochemistry confirmed. Intermediate (+)-4 was synthesized using either an asymmetric conjugate addition strategy, or by elaboration of the Hajos-Parrish ketone. Reduction of (+)-4 under dissolving-metal conditions and trapping the enolate intermediate served to control the cis-stereochemistry at the ring fusion and provide a silyl enol ether necessary for ring expansion. Comparison of optical rotation data confirmed that the absolute configuration of natural hortonone C is (6S,7S,10S).

Abstract
The addition of MeLi to boron enolates produced by the 1,4-addition of Ar2Cu(CN)Li2 to BF3·OEt2-activated enones was followed by the reaction with ClP(O)(OEt)2 to afford the corresponding enol phosphates in moderate to good yields. The scope of this method was examined with sterically hindered or electronically biased enones and/or reagents. This activation of boron enolates was successfully applied to the synthesis of the methyl ether of Δ(9)-tetrahydrocannabinol.

Abstract
![]()
The first enantioselective total
synthesis of (−)-nardoaristolone
B is accomplished by the implementation of an enantio- and diastereoselective
copper(I)-catalyzed conjugate addition/enolate trapping sequence and
a gold(I)-catalyzed oxidative cyclization (intermolecular oxidant),
employed for the first time in total synthesis.

Abstract
Under the influence of a chiral bidentate diphosphine ligand, the Pd-catalyzed asymmetric cross-coupling of allylboron reagents and allylic electrophiles establishes 1,5-dienes with adjacent stereocenters in high regio- and stereoselectivity. A mechanistic study of the coupling utilizing reaction calorimetry and density functional theory analysis suggests that the reaction operates through an inner-sphere 3,3'-reductive elimination pathway, which is both rate-defining and stereodefining. Coupled with optimized reaction conditions, this mechanistic detail is used to expand the scope of allyl-allyl couplings to allow the generation of 1,5-dienes with tertiary centers adjacent to quaternary centers as well as a unique set of cyclic structures.
