A Practical Method for the Preparation of 2-Arylbenzofurans and the Synthesis of Moracin A and B

Oxidative rearrangement of 2-benzyloxychalcones 2 with Tl(NO3)3 in methanol to 1,2-diaryl-3,3-dimethoxy-1-propanones 3, alkaline degradation to aryl 2-benzyloxybenzyl ketones 4, debenzylation, and ring closure gave 2-arylbenzofurans 1.In this way moracin A and B (1a, b), further 2-(2,4-dihydroxyphenyl)-5,6-dimethoxybenzofuran (1c) were synthesized.The latter was not identical with a substance isolated from Myroxylon balsamum for which structure 1c was claimed.
