    • When phenyl-substituted propargyl ester 1i was employed, the corresponding cycloaddition products were not obtained at all. The corresponding allene, generated through the 1,3-acyloxy rearrangement, and its hydrolyzed ketone were obtained as major products. The reactions of terminal propargyl ester 1j led to a complex mixture of products
