A 2-amino-1,3-propanediol compound represented by general formula (I) or a pharmaceutically acceptable salt thereof, and an immunosuppressant containing the same as the active ingredient. In said formula R represents optionally substituted linear or branched carbon chain, optionally substituted aryl or optionally substituted cycloalkyl; and R2, R3, R4 and R5, which may be the same or different from one another, represent each hydrogen, alkyl, aralkyl, acyl or alkoxycarbonyl. The compound is immunodepressant and useful as an inhibitor against rejection in organ or bone marrow transplantation, as a preventive or remedy for autoimmune diseases and so forth, or a reagent in the medical and pharmaceutical fields.

The construction of different types of substituted arenes was demonstrated through the photocyclization of 2-(fur-3-yl)ethenylarenes using a 3-furyl group as an isopropenyl equivalent synthon in the photocyclization reaction. The furan portion of the photocyclization intermediate could be fragmented via a base-induced elimination reaction to yield a series of substituted polyaromatics, including naphthalene
