Abstract : Triazole-gold(TA-Au) could catalyze propargyl vinyl ether undergo the Schmittel cyclization at room temperature while other tested [L-Au]+ catalysts produced no desired producted under identical conditions. What's more, sterically hindered groups (such as t-Bu) on allene termini were not necessary any more due to the employment of mild conditions, and this provided the chance to synthesize previously challenging substrates successfully.
