摘要：
A new heterocyclic fulgide: E-(alpha)-(1,2-dimethyl-4-isopropyl-5-phenyl)-3-pyrryl ethylidene (isopropylidene) succinic anhydride (1) has been synthesized. The molecular conformation and atomic labelling structure of (1) was obtained by X-ray analyses. Compound (1) shows a twisted structure between different ring systems. The short distance between C1 atom and C22 atom (3.567 Angstrom) offers a favourable structure for the photoinduced intramolecular cyclization of 1.
