An indolylfulgide derivative possessing an orthoester-type functional group on the acid anhydride moiety with a C2-symmetric (S,S)-1,2-bis(1-hydroxypropyl)benzene was prepared. Irradiation of 313-nm light produced the colored form in 90% diastereomer excess. The [α]D values for the colorless and the colored forms in toluene were +82° and −420°, respectively.
