Abstract
Homochiral acetylenic acids of general structure 10, prepared using th e Schreiber modification of the Nicholas reaction, have been converted to beta-amino acid derivatives of type 11 by a two step sequence invo lving Curtius rearrangement followed by oxidative cleavage of the acet ylenic bond. Amino acid derivatives 11 are excellent precursors for be ta-lactams of the carbapenem class.
