摘要：
A novel series of spirofused indoloquinuclidines was obtained by a tandem Pictet-Spengler/Au-I-catalyzed cyclization sequence. By combining N-propargyl tryptamine with aldehydes in the presence of acetic acid and a gold complex, the target indoloquinuclidines were obtained. The combination of a chiral phosphoric acid catalyst for the asymmetric Pictet-Spengler reaction with a gold complex furnished the target compounds with ee values up to 90 % in high diastereoselectivity.
