Abstract:
(+/-)-Streptovitacin A (1) and its stereoisomers were synthesized by an aldol reaction of (+/-)-2,4-dimethyl-4-trimethylsiloxy-1-cyclohexanones (4b and 9) with 4-(2-oxoethyl)-2,6-piperidinedione (5). E-72 (2) was derived from synthetic 1. (+/-)-1 showed moderate growth inhibition against fungi and lettuce seeds.
