Properties of derivatives of tricyclo[6,n,0,02,7]tri-2,4,6-enes. Abnormal reaction of toluene-p-sulphonic acid with 8,12-dimethyl- and 8-methyl-tricyclo[6,4,0,02,7]tri-2,4,6-en-1-ols. Synthesis of some anti-2,7-benzobicyclo[3,2,1]octene derivatives

Abstract

Structure (3a) has been assigned to a compound obtained in 85% yield, by the action of the toluene-p-sulphonic acid on 8,12-dimethyltricyclo[6,4,0,0^2,7]tri-2,4,6-en-1-ol (1c); the synthesis of some derivatives of anti-2,7-benzobicyclo[3,2,1]octen-12-ol is reported.
