(±)-Streptovitacin A (1) and its stereoisomers were synthesized by an aldol reaction of (±)-2, 4-dimethyl-4-trimethyIsiloxy-1-cyclohexanones (4b and 9) with 4-(2-oxoethyl)-2, 6-piperidinedione (5). E-73 (2) was derived from synthetic 1. (±)-1 showed moderate growth inhibition against fungi and lettuce seeds.
(±)-Streptovitacin A(1)及其立体异构体是通过 (±)-2,4-二甲基-4-三甲基硅氧基-1-环己酮(4b 和 9)与 4-(2-氧代乙基)-2,6-哌啶二酮(5)的醛醇反应合成的。(±)-1对真菌和莴苣种子的生长有中等程度的抑制作用。
