Abstract
AbstractChiral α-tertiary amines, a motif present in α,α-disubstituted α-amino acids, in a wide range of natural products, and many drugs and drug candidates, are important targets in organic chemistry. Among the possible strategies, 1,2-addition to chiral N-sulfinylketimines is one of the best routes to form chiral α-tertiary amines with a high level of stereoselectivity. In this review, we focus first on the addition of organometallic reagents or other nucleophiles as enols or ylides to chiral N-sulfinylketimines. Then secondly we cover a selection of applications of these additions in the synthesis of valuable biologically active compounds.1 Introduction2 1,2-Addition Reaction Methodologies2.1 Organolithium Reagent Additions2.2 Grignard Additions2.3 Organozinc Reagent Additions2.4 Organoindium Reagent Additions2.5 Organoboron Reagent Additions2.6 Strecker Reactions2.7 Palladium-Catalyzed Reactions2.8 Enols, Enolates, and Other Deprotonated Reagent Additions2.9 Ylide Additions2.10 Heteroatom Nucleophiles2.11 Miscellaneous Reactions3 Applications to the Synthesis of Biologically Active Molecules4 Conclusions

Abstract
The Thorpe–Ingold effect was applied to the design of a chiral ligand of π–copper(II) catalysts for the enantioselective α-fluorination of N-acyl-3,5-dimethylpyrazoles, and also for the enantioselective Mukaiyama–Michael, Diels–Alder, and 1,3-dipolar cycloaddition reactions of N-acryloyl-3,5-dimethylpyrazoles. The use of β,β-dimethyl-β-arylalanine-type ligand gave desired products with higher enantioselectivity compared to with previously reported β-arylalanine-type ligands.

Abstract
The incorporation of adamantylalanine and carboranylalanine at the P2 site of bortezomib is well tolerated and provided potent cell permeable proteasome inhibitors with increased off-rates compared to bortezomib. Adamantylalanine and carboranylalanine were synthesized enantioselectively by an asymmetric Strecker reaction on Ellmans tert-butyl sulfinimines.

Abstract
A series of 2-chlorotetrafluoroethanesulfinyl ketimines were prepared from 2-chlorotetrafluoroethanesulfinamide and ketones in high yields, and their Strecker reactions with TMSCN have been investigated. High yields and excellent diastereoselectivities were achieved in the presence of a catalytic amount of CsF under mild conditions. The six-membered chairlike models were proposed to account for the high stereoselective Strecker reaction.

Abstract
In this critical review, the ring opening of non-activated 2-substituted aziridines via intermediate aziridinium salts will be dealt with. Emphasis will be put on the relationship between the observed regioselectivity and inherent structural features such as the nature of the C2 aziridine substituent and the nature of the electrophile and the nucleophile. This overview should allow chemists to gain insight into the factors governing the regioselectivity in aziridinium ring openings (81 references).

Abstract
Mannich-type addition of benzophenone imine glycinates across newly synthesized N-(p-toluenesulfonyl) alpha-chloroaldimines afforded gamma-chloro-alpha,beta-diamino ester derivatives with moderate diastereoselectivity as separable mixtures of anti and syn diastereomers. The gamma-chloro-alpha,beta-diamino esters were efficiently cyclized under basic conditions to the corresponding beta,gamma-aziridino alpha-amino ester derivatives, representing a new class of conformationally constrained heterocyclic alpha,beta-diamino acid derivatives. The relative configuration of the aziridines was determined via X-ray diffraction analysis. Mechanisms and intermediate transition states to explain the stereochemical outcome of the Mannich reaction with different substrates or under different conditions are proposed. The synthetic importance of the beta,gamma-aziridino alpha-amino ester derivatives is demonstrated by their conversion into the corresponding Boc-protected derivatives and ring opening reactions to alpha,beta-diamino esters and a gamma-amino alpha,beta-unsaturated amino ester.

Abstract
Enantiomerically pure alpha-substituted alpha-amino phenylacetonitriles have been readily prepared from 2-p-tolylsulfinylbenzaldimines following a two-step sequence: a moderately stereoselective hydrocyanation of the imines and a completely stereoselective quaternization of the resulting diastereoisomeric mixture of alpha-amino phenylacetonitriles with different alkylating or acylating reagents in the presence of KHMDS. Theoretical calculations support a stereoselectivity control exerted by the remote sulfinyl group, as long as it is responsible for the conformational preferences of the benzyllithium intermediates, which suffer the attack of the electrophiles to the less hindered diastereotopic face.
