A considerably improved iron-mediated synthesis leads to the marine carbazole alkaloid hyellazole on large scale in eight steps and 63% overall yield from 2,6-dimethoxytoluene. The first conversion of hyellazole into 6-chlorohyellazole has been achieved a

We described a new seven-stage synthesis of the carbazole alkaloids hyellazole and 6-chlorohyellazole, which proceeds via thermal cyclization of the 3-(buta-1,3-dienyl)indoles 7ab and 7bb, prepared from the condensation products of indole-2,3-diones 1a, b and the 3-methyl-4-phenylbut-3-en-2-one 2b.This procedure was also used to prepare related 3-methoxy-1-phenylcarbazole derivatives.
