Synthesis of γ-Arylmethylene-aminopropyl-3,7,10-trimethyl-silatrane Derivatives and Their Activities of Regulating Plant Growth

Abstract

Five novel γ-arylmethylene-aminopropyl-3,7,10-trimethyl-silatrane derivatives and three novel γ-arylmethylene-aminopropyl-silatrane derivatives were synthesized, and their activities of regulating the plant growth in culture dishes were tested. The compounds showed good activities of regulating the root/stem growth on turnips of amphibrya and corns of dicotyledon at a concentration of 40 ppm. Moreover, the activities of two were stronger than that of brassinolide, the positive control, while those of the remainder were not obvious. The activities of regulating plant growth of derivatives with a methyl group on the ring were stronger than those of derivatives with no methyl substituent.
