A Practical and Robust Zwitterionic Cooperative Lewis Acid/Acetate/Benzimidazolium Catalyst for Direct 1,4-Additions. Angew Chem Int Ed Engl 2023; 62:e202217519. [PMID: 36651714 DOI: 10.1002/anie.202217519] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2022] [Revised: 01/17/2023] [Accepted: 01/18/2023] [Indexed: 01/19/2023]
Abstract
A catalyst type is disclosed allowing for exceptional efficiency in direct 1,4-additions. The catalyst is a zwitterionic entity, in which acetate binds to CuII , which is formally negatively charged and serving as counterion for benzimidazolium. All 3 functionalities are involved in the catalytic activation. For maleimides productivity was increased by a factor >300 compared to literature (TONs up to 6700). High stereoselectivity and productivity was attained for a broad range of other Michael acceptors as well. The polyfunctional catalyst is accessible in only 4 steps from N-Ph-benzimidazole with an overall yield of 96 % and robust during catalysis. This allowed to reuse the same catalyst multiple times with nearly constant efficiency. Mechanistic studies, in particular by DFT, give a detailed picture how the catalyst operates. The benzimidazolium unit stabilizes the coordinated enolate nucleophile and prevents that acetate/acetic acid dissociate from the catalyst.

Abstract
The highly asymmetric Michael addition reaction between maleimides and aliphatic aldehydes catalyzed by low-loading β-turn tetrapeptides with excellent yields and enantioselectivities at room temperature was reported. α-Branched and α-unbranched aldehydes both are suitable nucleophiles. N-Aryl, alkyl and hydrogen maleimides all are well tolerated and led to high yields and enantioselectivities. The transformation can be enlarged to the gram scale without decrease in the yield and enantioselectivity. Furthermore, the succinimides were converted into γ-lactams and γ-lactones, showing good practicality of this work. Some reaction intermediates in the proposed reaction mechanism can be captured with the HR-MS method.

Abstract
:
Many catalysts were tested in asymmetric Michael additions in order to synthesize
enantioenriched products. One of the most common reaction types among the Michael
reactions is the conjugated addition of malonates to enones making it possible to investigate
the structure–activity relationship of the catalysts. The most commonly used Michael
acceptors are chalcone, substituted chalcones, chalcone derivatives, cyclic enones,
while typical donors may be dimethyl, diethyl, dipropyl, diisopropyl, dibutyl, di-tert-butyl
and dibenzyl malonates. This review summarizes the most important enantioselective
catalysts applied in these types of reactions.

Abstract
N,N'-Dialkylbarbituric acids as cyclic malonamide donors were successfully used in the enantioselective Michael addition reaction of enones. Using cinchona alkaloid-based bifunctional squaramide as an organocatalyst, this Michael reaction of N,N'-di-tert-butylbarbituric acid with various enones features a highly enantioselective (91-99% ee) production of the corresponding optically active 5-substituted barbituric acid derivatives. The transformations of the Michael product for the barbituric acid structural unit were realized in two ways, deprotection to remove the N-tert-butyl group and alkylation to produce 5,5-disubstituted barbituric acid derivatives.

Abstract
To illustrate the general principle of asymmetric organocatalysis of chiral bicyclic guanidine, a density functional theory study was carried out to examine the catalytic mechanism, activation mode, origin of stereoselectivity of a [5,5]-bicyclic guanidine-catalyzed Michael addition of dimethyl malonate to 2-cyclopenten-1-one. Two types of bifunctional activation modes were examined: Brønsted acid and Brønsted-Lewis acid. The calculated enantioselectivity (ee), based on eight C–C bond forming transition states and their pre-transition state complexes, is in excellent accord with experimental result. The ternary pre-transition state complexes are stable species, which strongly influence the stereoselectivity. Similar to enzyme catalysis, the bicyclic guanidinium catalyst plays an essential recognition role in assembling the substrates together via hydrogen bonds, multiple C–H···O interactions (as oxyanion hole), donor–acceptor, and electrostatic interactions.

Abstract
The catalytic mechanism and origin of enantioselectivity of bicyclic guanidine-catalyzed phospha-Michael reaction between diphenyl phosphine oxide and β-nitrostyrene were investigated by DFT calculations at M06-2X/cc-pVTZ//M06-2X/cc-pVDZ level in conjunction with the implicit SMD solvation method. The catalyst is found to be involved in all 3 steps of the proposed catalytic cycle, namely (1) tautomerization of phosphine oxide, (2) C-P bond formation and (3) concerted hydrogen transfer. The bifunctional role of the guanidine catalyst is clearly demonstrated in all 3 key steps. Due to the geometry of the bicyclic guanidine catalyst, the preferred orientation of the reactants in the transition state of enantioselective C-P bond forming step favours the R enantiomer, in excellent accord with the observed enantioselectivity. Analysis of various transition states suggests that the asymmetric C-P bond formation is controlled by the hydrogen bonding interaction and steric effect between the catalyst and substrate. Various weaker C-H···X (X = N, O and π) interactions also play a role in stabilizing the key transition states.
