(+/-)-Daunomycinone and (+/-)-4-demethoxydaunomycinone have been synthesized via two successive Diels-Alder reactions from naphthazarin. Key steps for the construction of the A-ring of the anthracyclinone are the Diels-Alder reaction of the BCD fragments with 1-tert-butoxy-3-trimethylsilyloxybuta-1,3-diene and further functionalisation of the hydrolysed product with trimethylsilylethynyl lithium, these
(+/-)-Daunomycinone和(+/-)-4-demethoxydaunomycinone是通过萘普沙林的两个连续的Diels-Alder反应合成的。构建蒽环素A环的关键步骤是BCD片段与1-叔丁氧基-3-三甲基甲硅烷氧基丁氧基1,3-二烯的Diels-Alder反应以及水解产物与三甲基甲硅烷基乙炔基锂的进一步官能化,这些步骤允许蒽环素的多谱合成,对A环的7,9-羟基具有很高的顺式选择性。
