A new route for synthesis of 6-deoxyanthracyclinone has been developed. Preparation of the key intermediate 2-ethylenedioxy-9-pivaloyloxy-1,2,3,4-tetrahydroanthracene-5,8-dione was achieved by chemoselective reduction of the adduct of naphthazarin monopivalate with 1-methoxy-3-trimethylsiloxybutadiene, and successive dehydration of the resulting alcohol.
开发了合成6-脱氧蒽环酮的新路线。关键中间体2-亚乙基二氧基-9-新戊酰氧基-1,2,3,4-四氢蒽-5,8-二酮的制备是通过对萘甲素单新戊酸酯与1-甲氧基-3-三甲基甲硅烷氧基丁二烯的加合物进行化学选择性还原,并连续得到的酒精脱水。
