Catalytic asymmetric synthesis of cyclic α-alkyl-amino acid derivatives by C,N-double alkylation
摘要:
Catalytic asymmetric synthesis of various cyclic alpha-alkyl-amino acid derivatives having a tetrasubstituted alpha-carbon, such as alpha-alkylprolines has been accomplished by asymmetric phase-transfer C-alkylation of alpha-alkyl-amino acid derivatives and subsequent intramolecular N-alkylation.
