A convenient route to the daunomycinone precursor 18via a succession of Diels-Alder reactions from 2,7-dichloronaphthazarin (9) is described. In a similar manner, starting from 2,6-dichloronaphthazarin (19) compound 20, a regioisomer of 18,is synthesized. This methodology constitutes a regiospecific approach to (±)-daunomycinone and related anthracyclinones.
描述了通过2,7-二氯萘他林(9)的一系列Diels-Alder反应到达道诺霉素前体18的便捷途径。以类似的方式,由2,6- dichloronaphthazarin(起始19)化合物20,的区域异构体18,被合成。该方法学构成了对(±)-金牛烯酮和相关蒽环素的区域特异性方法。
