manzamine-related alkaloids, ircinols A (1) and B (2), have been isolated from the Okinawan marine sponge Amphimedon sp. and the structures elucidated to be enantiomers of alcoholic forms at C-1 of ircinals A and B, respectively, on the basis of extensive 2D NMR data and chemical correlations. Compounds 1 and 2 are the first examples possessing opposite absolute configurations to those of manzamine alkaloids.
从冲绳海洋海绵Amphimedon sp。中分离出两种新的与山z胺有关的生物碱,ircinols A(1)和B(2)。根据广泛的2D NMR数据和化学相关性,阐明了分别在ircinals A和B的C-1处为醇形式对映体的结构。化合物1和2是具有与山z胺生物碱的绝对构型相反的绝对构型的第一个实例。
