The crystalline sulfone 18 (X-ray analysis), prepared from the monoacetate product [i.e., (+)-12; 98.2% ee] of the lipase PS-catalyzed acetylation of anti,anti-2,4-dimethyl-1,3,5-pentantriol (19a), has been elaborated either to crocacin C (10) or stigmatellin (1), thereby providing a convenient divergent access to these two natural antibiotics.
通过晶体硫砜 18(X 射线分析),由脂肪酶 PS 催化的反反-2,4-二甲基-1,3,5-戊三醇(19a)的单乙酸酯产物 [即(+)-12;98.2% 对映体过量] 制备,已分别详细阐述为藏红花素 C(10)或柱头霉素(1),从而为这两种天然抗生素提供了一个便捷的分支途径。
