Silyl modification of biologically active compounds. 9. synthesis and biological activity of novel 1,3-disilabenzo[5,6]cyclohexene derivatives

摘要

We have synthesized a series of 1,3-disilabenzo[5,6]cyclohexene derivatives starting from (o-bromomethylphenyl)dimethylchlorosilane. Based on NMR data, we have concluded that there is a transannular N->Si interaction in the 3',3'-5-trimethyl-2,8-dioxa-5-aza-1-silacyclooctane-1-spiro-1'-(1',3'-disilabenzo-[4',5']cyclohexene) obtained. We have studied the psychotropic activity of this compounds and its iodomethylate and also 3-(3-chloropropyl)-1,1,3-trimethyl-1,3-disilabenzo[5,6]cyclohexene, and we have shown that they have a sedative effect.
