摘要：
Chiral 2-triflyloxy esters, prepared from chiral 2-hydroxy esters, react enantiospecifically wilh BocNHNH2 to produce optically pure 2-hydrazinyl ester derivatives in high yields. The reaction of 2-nosyloxy esters with BocNHNH2 gives 2-(Bochydrazinyl) esters, thus providing an efficient (albeit slow) method for the conversion of esters to 2-hydrazinyl ester derivatives. © 1990.
