摘要:
Trifluoromethyl substituted alpha-amino acid derivatives 4, 5 having a diene function in the side chain are obtained on reaction of 5-fluoro-4-trifluoromethyl-oxazole 1 with allylic alcohols of the 3-hydroxypenta-1,4-diene type. Via 4 and 5 introduction of carbocyclic and heterocyclic systems into the side chain of alpha-amino acids can be achieved by [4 + 2] cycloaddition.
