A radical-organometallic glycine synthon. Preparation of homochiral heterocyclic α-amino acids
摘要:
Co)Acac)2 reacts with (1) and (d)-menthyl N-BOC-2-bromoglycinates to give (1)- and (d)-menthyl N-BOC 3-acetylnorvalinates, which are converted into homochiral 2-(3,5-dimethyl-4-pyrazolyl)glycine and 2-(3,5-dimethyl)-4-isoxazolylglycine.
The synthesis of α-pyrazolylglycine derivatives(7a-d) with different substituents, starting from glycine have been pre pared. The spectroscopy of intermediate compounds and the final amino acids have been discussed.
