摘　　要：A new heterocyclic fulgide:E-(α)-(1,2-dimethyl-4-isopropyl-5-phenyl)-3-pyrryl ethylidene (isopropylidene)succinic anhydride(1) has been synthesized.Themolecular 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 beteen C1 atom and C22 atom(3.567A) offers a favourable structure for the photoinduced intramolecular cyclization of 1.A new heterocyclic fulgide:E-(α)-(1,2-dimethyl-4-isopropyl-5-phenyl)-3-pyrryl ethylidene (isopropylidene)succinic anhydride(1) has been synthesized.Themolecular 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 beteen C1 atom and C22 atom(3.567A) offers a favourable structure for the photoinduced intramolecular cyclization of 1.
