Chemistry 2024; 30:e202400363. [PMID: 38376252 DOI: 10.1002/chem.202400363] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2024] [Revised: 02/19/2024] [Accepted: 02/20/2024] [Indexed: 02/21/2024]
Abstract
Herein we describe a sustainable and efficient photocatalytic method for the stereoselective radical alkylation of chiral sulfinyl imines. By employing readily available non-prefunctionalized radical precursors and the cost-effective TBADT as a direct HAT photocatalyst, we successfully obtain diverse chiral amines with high yields and excellent diastereoselectivity under mild conditions. This method provides an efficient approach for accessing a diverse array of medicinally relevant compounds, including both natural and synthetic α-amino acids, aryl ethyl amines, and other structural motifs commonly found in approved pharmaceuticals and natural product.

Abstract
A series of α-mercapto-β-amino acid derivatives were synthesized diastereoselectively in good yields through the aza-enolization of α-sulfanyl N-tert-butanesulfinylimidates, followed by their nucleophilic addition to N-tosyl imines via a Mannich-type reaction. The resulting derivatives bearing a β-sulfonylamino sulfide moiety participated in further inter- and intramolecular transformations involving episulfonium ion intermediates generated through neighboring-group participation.

Abstract
2-, 3- and 4-Bromopyridine, along with other brominated electron-deficient arenes, undergo palladium-catalyzed coupling with ureas of structure RNMeCONHMe. Where R is a chiral, alpha-substituted benzyl group, treatment with LDA leads to a benzylic organolithium which undergoes rearrangement with stereospecific and regiospecific transfer of the pyridyl group, generating a quaternary stereogenic center with high enantioselectivity. Alcoholysis of the urea under neutral conditions reveals the pyridyl amine.

Abstract
A revisited synthesis of 2-aryl-6-methyl-1,2-dihydro-1H-pyridin-4-ones and their saturated analogues 2-aryl-6-methylpiperidin-4-ols is described. A five steps procedure, using the sulfinimine chemistry, to prepare a key intermediate beta-(6-chloronicotinic)-beta-amino ester is also reported. In vivo spontaneous working memory activity of these compounds has been investigated in the mouse. Results obtained with 2-(3-chlorophenyl)-6-methyl-1,2-dihydro-1H-pyridin-4-one 9b, the most effective derivative in this model, have been reported.

Abstract
The unprecedented application of unmodified aldehydes as nucleophilic donors in direct catalytic asymmetric Mannich-type reactions is disclosed in a full account. Our efforts in broadening the applicability of chiral pyrrolidine-based catalysts in direct asymmetric Mannich-type reactions led to the highly diastereo- and enantioselective and concise synthesis of functionalized alpha- and beta-amino acids, beta-lactams, and amino alcohols.

Abstract
The enantiopure Davis' N-sulfinylimines were found to be efficient as chiral imine equivalents in the high-temperature Reformatsky-type additions with BrZnCF(2)COOEt affording an efficient approach to the enantiomerically pure alpha,alpha-difluoro-beta-amino acids. High chemical and stereochemical yields (drs > 9:1, and as high as 99:1) render this method immediately useful for preparing the target amino acids.

Abstract
[reaction: see text] Rh-Me-BDPMI (1a) complex can be an effective catalyst for the hydrogenations of (E)- and (Z)-beta-(acylamino)acrylates, in which the Z-isomers hydrogenated with the same or even higher ee values than the corresponding E-isomers. The conversion yield and enantioselectivity of E- and Z-isomers were largely dependent on the solvent, and thus, the E-isomers were hydrogenated more effectively in CH(2)Cl(2), whereas the Z-isomers were hydrogenated more effectively in polar MeOH solvent.

Abstract
A novel family of chiral ortho-substituted BINAPO ligands (o-BINAPO) were synthesized from BINOL, and their Ru complexes were highly efficient catalysts for asymmetric hydrogenation of beta-aryl-substituted beta-(acylamino)acrylates and beta-aryl-substituted beta-keto esters. The Ru-bisphosphinite catalysts can tolerate an E/Z mixture of beta-aryl-substituted beta-(acylamino)acrylates. These highly enantioselective hydrogenations provide a useful way to prepare beta-aryl-substituted beta-amino acids and beta-hydroxyl acids.

Abstract
We introduce here a strategy that enables effective addition of lithium enolates of acetates to aldimines. The new method depends strongly on the use of o-alkoxy (or o-fluoro) aniline-derived aldimines which have been found to have a potential effect on the enolate addition. This scope was expanded to the asymmetric process using the chiral acetate. A Lewis acid additive has a complementary role in the pronounced activation of imine functionalities.

Abstract
The influence of N-sulfinyl chiral auxiliaries on the stereochemistry of the Pictet-Spengler reaction has been investigated. From enantiopure (R)-N-p-toluenesulfinyltryptamine a new and efficient route to enantiopure tetrahydro-beta-carbolines has been established.

Abstract
The addition of the lithium anions derived from (R)- and (S)-methyl and -ethyl p-tolyl sulfoxides to (S)-N-benzylidene-p-toluenesulfinamide provides an easy access route to enantiomerically pure beta-(N-sulfinyl)amino sulfoxides. Stereoselectivity can be achieved when the configurations at the sulfur atoms of the two reagents are opposite (matched pair), thus resulting in only one diastereoisomer, even for the case in which two new chiral centers are created. The N-sulfinyl group primarily controls the configuration of the carbon bonded to the nitrogen, whereas the configuration of the alpha-sulfinyl carbanion seems to be responsible for the level of asymmetric induction, as well as for the configuration of the new stereogenic C-SO carbon in the reactions with ethyl p-tolyl sulfoxides. An efficient method for transforming the obtained beta-(N-sulfinyl)amino sulfoxides into optically pure beta-amino alcohols, based on the stereoselective non-oxidative Pummerer reaction, is also reported.

Abstract
Lithium dienolate of 3-butenoic methyl ester was reacted with enantiomerically pure N-arylsulfinyl phenylimines (1 and 2) under different conditions. The reactions were completely regioselective-the C-C coupling occurs at the 2-position of dienolate-and highly stereoselective at the iminic carbon. In the presence of different Lewis acids (ZnCl(2), ZnBr(2), and ScTf(3)) mixtures of two alpha-vinyl, beta-arylsulfinylamino esters (epimers at C-alpha) were obtained, being the stereoselectivity depending on the nature of the aryl sulfinyl moiety and the Lewis acid used. Desulfinylation of these mixtures followed by isomerization of the double bond with Na(2)CO(3) allowed the synthesis of the optically pure (E)-alpha-ethylidene-beta-amino ester 10 in quite high overall yield. The addition of the lithium dienolate to sulfinylimines in the absence of the Lewis catalysts yielded mixtures containing important amounts of the optically pure N-arylsulfinyl alpha-ethylidene-beta-amino esters, which became the exclusive product of the reaction when N-2-methoxynaphthylsulfinyl phenylimine 2 was used as starting product.
