The first examples of a highly efficient and enantioselective carbene-mediated insertion reaction, from a sulfur ylide, are described. By way of a catalytic asymmetric insertion reaction into N-H bonds from carbonyl sulfoxonium ylides and anilines, using a copper-bifunctional squaramide cooperative catalysis approach, thirty-seven α-arylglycine esters were synthesized in enantiomeric ratios up to 92?:?8 (99?:?1 after a single recrystallization) and reaction yields ranging between 49-96%. Furthermore, the protocol benefits from quick reaction times and is conducted in a straightforward manner.

A series of N-substituted amino acid derivatives was synthesized and the compounds were evaluated for their effects on serum total cholesterol, HDL cholesterol and triglycerides in experimental animals.Hyperalphalipoproteinaemic activity was found for some of these compounds tested, especially BRL 26314 (2) and related 3-aryl-2-aminopropionic acids.Structure-activity relationships are discussed.Keywords: N-substituted amino acid derivatives / hyperalphalipoproteinaemic activity
