  Synthesis of some analogues of blattellastanoside A, the steroidal aggregation pheromone of the German cockroach

  摘要：

  Blattellastanoside A, the aggregation pheromone of the German cockroach, is a chlorinated steroid glucoside with the 5 beta-stigmastane skeleton. Its analogues were synthesized in order to clarify the structure-activity relationship. They are 1a with the 5 beta-cholestane skeleton, 1b with the 5 beta-androstane skeleton, Ic with a fluorine substituent instead of the chlorine and Id with a beta-D-galactopyranose instead of the beta-D-glucopyranose of the original pheromone. Their bioassay shows that la and Ic are active, while Ib and Id are totally devoid of pheromone activity. The aglycone of blattellastanosides A and B were active.
