摘要：

The title pale yellow photochromic compound 11b in toluene, on irradiation at 366 nm, cyclises to the thermally stable infrared active blue-green photochrome, 8-amino-7-cyano-4,4-dicyclopropyl-3a,4-dihydro-6-hydroxy-2,3a-dimethylnaphtho[2,1-b]furan-5,6-carbolactone, 12b which has a lambda(max) value of 720 nm for its broad long wavelength absorption band.
