Ieodomycin B, which shows in vitro antimicrobial activity, was isolated from a marine Bacillus species. A novel asymmetric total synthetic approach to ieodomycin B using commercially available geraniol was achieved. The approach involves the generation of 1,3-trans-dihydroxyl at C-3 and C-5 positions via a Crimmins-modified Evans aldol reaction and a chelation-controlled Mukaiyama aldol reaction of
从海洋芽孢杆菌中分离出具有体外抗菌活性的伊霉素B。实现了一种新的不对称全合成方法,即使用市售的香叶醇制备伊多霉素B。该方法涉及通过Crimmins修饰的Evans aldol反应和对甲氧基苄基保护的醛的螯合控制的Mukaiyama aldol反应在C-3和C-5位置生成1,3-反式二羟基,以及脱保护-内酯化一锅反应中内酯环的生成。
