摘要

Abstract Photorearrangements of o-methoxystilbenoils (1a-1c) in acid media have been investigated. Irradiation of o-methoxystilbene (1c), for example, could lead to three major rearrangement products: 2, 3, 4-trihydrophenanthren-1-ones (2c), trans-1-arylbut-2-en-1- ones (3c), and 1-hydroxy-9, 10-dihydrophenanthrenes (7). Further irradiation of trans-1- arylbut-2-en-1-ones (3) could afford three more products (4, 5 and 6). The key step for this ...
