of LY354740 were accomplished employing an N-Boc acylnitroso Diels−Alder cycloadduct as the starting material. The syntheses involved N−O bond cleavage, oxidation, intermolecular cyclopropanation, Bucherer−Bergs reaction, hydrolysis, and regioselective acylation with a temporary copper chelate. The synthesis of an optically active compound was also achieved.
使用N -Boc酰基亚硝基Diels-Alder环加合物作为起始原料,可以完成LY354740的4-酰基氨基类似物的简明合成。合成涉及N - O键断裂,氧化,分子间环丙烷化,Bucherer-Bergs反应,水解和与暂时性铜螯合物的区域选择性酰化。还实现了光学活性化合物的合成。
