Photochemical transformations of cyclic azimines–X-ray crystallographic analysis of intermediates in their sequential phototransformations
Abstract
A series of sequential transformations on irradiation of the readily available cyclic azimines 2 lead to saturated pyrrolo[2,3-b]indoles 3, the mechanism of which is confirmed by isolation of photolabile intermediates 4 and 7 and two crystallographic determinations.
