synthesized from oripavine by a sequence involving the conversion of oripavine into its cyclopropylmethyl quaternary salt, N-demethylation with thiolate to N-cyclopropylmethyl nororipavine, and conversion of this material to the title compound by previously available methods. The new synthesis avoids toxic reagents used previously, is shorter, and proceeds in comparable yields. Experimental and spectral data
丁丙诺啡是通过以下顺序从兽皮中合成的,该序列涉及将兽皮中的碳转化为其环丙基甲基季盐,用硫醇盐进行N-脱甲基化为N-环丙基甲基去甲紫罗兰,然后通过先前可获得的方法将该物质转化为标题化合物。新的合成方法避免了以前使用的有毒试剂,时间更短,并且收率相当。提供了所有新化合物的实验数据和光谱数据。
