摘要：

A photochromic furylfulgide, (E)-2-[1-(2,5-dimethyl-3-furyl)-2-methylpropylidene]-3-isopropylidenesuccinic anhydride, was shown to be chiral. Its enantiotopomerization process was observed by variable temperature H-1 NMR measurement, and Delta H not equal(obs) was 52.9 +/- 8.1 kJ mol(-1). AM1 calculation showed Delta H not equal(calc) to be 51.5 W mol(-1).
