(+/-)-Illudin M (1) was synthesized in six steps starting from 1-acetyl-1-(diazoacetyl)cyclopropane (4) and 4-bromo-5,5-dimethyl-2-cyclopentenone (5). The key step of the synthesis featured a carbonyl ylide 1,3-dipolar cycloaddition reaction that was mediated by the formation of a rhodium(II) carbenoid from 4 and catalytic rhodium(II) diacetate.
以1-乙酰基-1-(叠氮乙酸基)环丙烷(4)和4-溴-5,5-二甲基-2-环戊烯酮(5)为起始原料,经过六步反应合成了(+/-)-伊卢丁 M(1)。其中的关键步骤是通过4与催化量的铑(II)二乙酸盐生成的铑(II)卡宾介导,完成了一个羰基烯胺的1,3-二极环加成反应。
