## 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
