Photochemical Transformations of Methoxyphthalaldehydic Esters: Synthesis of Methyl 6-Methoxyphthalaldehydate from the 3-Methoxy-isomer

Jung, Michael E.,Blum, Roberto B.

, p. 962 - 963 (1981)

Irradiation of the 3-methoxyphthalaldehydate (4a) in methanol gives an excellent yield of the methoxyphthalide (1c) which can be converted into the 6-methoxyphthalaldehydate (3a) in excellent yield, thus effecting an 'isomerization' of the original phthal
