the ring-expanded ketone as corresponding α-, and β-substituents, respectively. This novel thermal 1,3-C shift reaction therefore provides a new access to short syntheses of many alkyl-substituted macrocyclic ketone derivatives [e.g. (′)-muscone and analogues] in a systematic manner.
在 600 °C 至约 650 °C 的温度下,1-乙烯基取代的中环和大环环烷醇衍生物在流动反应器系统中的热异构化直接导致扩环大环酮。乙烯基部分的烷基取代基分别作为相应的α-和β-取代基局部特异性地转移到扩环的酮上。因此,这种新颖的热 1,3-C 变换反应为许多烷基取代的大环酮衍生物 [例如 (')-麝香酮和类似物] 以系统方式进行短程合成提供了新途径。
