N-BOC protected α-hydrazinoketones 4 and N-tris protected α-aminoketones 6 were synthesized in good overall yields by deprotonation and electrophilic amination of the corresponding ketone-N,N-dimethylhydrazones2 and subsequent oxidative cleavage of the resulting product hydrazones 3 and 5 by ozonolysis.
N -BOC保护的α-肼基酮4和N -tris保护的α-氨基酮6通过相应的酮-N,N-二甲基hydr酮2的去质子化和亲电胺化以及随后的氧化反应生成的基3和7进行氧化裂解,以高收率合成了N -BOC保护的α-肼基酮4和N -tris保护的α-氨基酮6。5通过臭氧分解。
