Abstract

A general route to 3-substituted cyclohepta-1, 4-dienes is described in this paper. 7- Substituted cycloheptatrienes were used as starting materials and these were reacted with 4- phenyl-1, 2, 4-triazoline-3, 5-dione to give 4+ 2 cycloaddition products of the norcaradiene form of the cycloheptatrienes. Catalytic reduction of these adducts gave 9-substituted 4- phenyl-2, 4, 6-triazatetracyclo [5.3. 2.02, 6.08, 10] dodeca-3, 5-diones in good yield. Basic ...
