intramolecular Rauhut–Currierreaction utilizing alkynoates as the initial conjugate acceptor affords densely functionalized 5- and 6-membered rings from ynoate-enoate, ynoate-enenitrile, and alkynyl sulfone-enenitrile substrates. Trialkylphosphines catalyze the reaction, and TMSCN serves as a pronucelophile to effect turnover of the catalyst and the formation of a second C–C bond. Because of the highly electrophilic
