摘要

Abstract Lewis acid catalyzed cyclization of trichloroacetimidates derived from 1, 4- butenediols and 1, 5-butenediols was achieved to give 4-vinyl oxazolines and 4- vinyloxazines in good to excellent yields. The cyclization products were transformed to protected unsaturated α-and β-amino acids, thus demonstrating the novel approach to access these important classes of compounds.
