O-methyl-3-acyl tetronates were prepared in good yield from the corresponding acid chlorides via a palladium catalyzed acylation of O-methyl 3-(tri-n-butylstannyl) tetronates 5. This new synthetic method was then exploited for the total synthesis of the novel antibiotic agglomerin A 3a, as well as the fungal metabolite (±) carolinic acid 15.
通过钯催化的O-甲基3-(三正丁基锡烷基)四羧酸酯5的钯催化酰化反应,可以从相应的酰氯中以高收率制备出各种O-甲基-3-酰基四羧酸酯。然后,这种新的合成方法被用于新型抗生素团聚蛋白A 3a以及真菌代谢产物(±)卡洛林酸15的全合成。
