Friedel-Crafts .alpha.-aminoacylation of alkylbenzene with a chiral N-carboxy-.alpha.-amino acid anhydride without loss of chirality
摘要:
A Friedel-Crafts-type alpha-aminoacylation of alkylbenzene with N-carboxy anhydrides Of five L-alpha-amino acids was developed. Five new alpha-aminoalkyl p-methylphenyl ketones and other alpha-aminoalkyl aryl ketones were obtained and isolated as free bases or hydrochloride salts. The chiralities of the original L-alpha-amino acids were retained during this acylation.
