ofregiochemistry in the Diels-Alder reactions of substituted naphthazarins is described. Application of this strategy to the synthesis of(±)-daunomycinone (2) employs two successive regiochemically controlled Diels-Alder reactions and leads to a ten-step, regiospecific synthesis of(±)-2 in 36% overall yield (Scheme 4).
描述了控制取代萘酚的狄尔斯-阿尔德反应中区域化学的一般策略的发展。该策略在合成(±)-柔顺霉素(2)中的应用采用了两个连续的区域化学控制的Diels-Alder反应,并导致了10步的区域特异性合成(±)-2,总产率为36%(方案4) 。
