Two new gold-catalyzed annulations of isoxazoles with propiolates have been developed. Most isoxazoles follow an initial O attack on the alkyne to afford a [4+1] annulation product. This process results in a remarkable alkyne cleavage of initial propiolates. Unsubstituted isoxazoles proceed through an N attack step to yield formal [2+2+1]/[4+2] annulation products. These two annulation products arise initially from two seven-membered heterocyclic intermediates, which then lead to products.

A direct transition-metal-free synthesis of 2-benzoylpyrrole derivatives from free (N-H) pyrroles and benzaldehyde has been developed. The benzoylation reaction at the 2 or 5-position of pyrrole proceeded well under the alkali metalation system and with 2
