have been conducted to investigate the reactivity of several bicyclic δ-hydroxynitriles with triflic anhydride in dichloromethane. The reactions of the analogues derived from 1-indanone and 1-tetralone lead to annulated enones. These products arise from an initial elimination reaction that generates an alkene, followed by the addition of the carbon−carbon double bond to the activated cyano group. The intramolecular
