radical cyclization of the acyl selenide 8, using a Z-vinylogous sulfonate to control rotamer population, affords the cis-2,6-disubstituted tetrahydropyran-4-one 9, applicable to the potent antitumor agent mucocin 1, in 81% yield.
使用Z-乙烯基磺酸盐控制rotamer种群,对酰基硒化物8进行分子内酰基自由基环化,可得到81%的顺式-2,6-二取代的四氢吡喃-4-酮9,适用于有效的抗肿瘤剂粘菌素1。屈服。
