Three new indole alkaloids, leptoclinidamines A−C (1−3), were isolated from the Australian ascidian Leptoclinides durus. Their structures were determined by analysis of 2D NMR spectra. Leptoclinidamines A and B both contain an indoleglyoxylic acid attached to an l-arginine. The structure of leptoclinidamine A was confirmed by total synthesis. Leptoclinidamine C contains the naturally rare 1,3-dime
