叔丁基[1-(对溴苯基)环丁基]氨基甲酸酯与N-甲基-N-甲氧基-苄酰胺在正丁基锂的作用下,经Weinreb酮合成法合成了抗癌药物二氮杂萘衍生物的关键中间体——叔丁基{1-[(对苯乙酰基)苯基]环丁基}氨基甲酸酯,收率33%,其结构经1H NMR确证。
A key anti-cancer drug intermediate,t-butyl{1-[(p-phenylacetyl)phenyl]cyclobutyl}carbamate,was synthesized in yield of 33% by the Weinreb ketone synthesis method of t-butyl[1-(p-bromophenyl)cyclobutyl]carbamate with N-methyl-N-methoxy-2-phenylacetamide in the presence of n-BuLi.The structure was confirmed by 1H NMR.
