✦ Synopsis
Abstract
Three new polybrominated 1__H__‐indoles, compounds 1–3, and three new aristolane sesquiterpenes, compounds 4–6, were isolated from the marine red alga Laurencia similis, together with seven known natural products. Their structures were elucidated on the basis of detailed spectroscopic and mass‐spectrometric analyses, as well as by comparison with literature data.
