Natural Benzofurans. Synthesis of Methylsainfuran and Sainfuran

2-(2,4-Dimethoxyphenyl)-5-hydroxy-6-methoxybenzofuran (methylsainfuran) and 2-(2-hydroxy-4-methoxyphenyl)-5-hydroxy-6-methoxybenzofuran (sainfuran).Insect feeding deterrent extractives of sainfoin, have been synthesized by a pathway in which the benzofuran heterocycle is formed by an interamolecular Wittig reaction.

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.

TWO 2-ARYLBENZOFURANS AS INSECT FEEDING DETERRENTS FROM SAINFOIN (ONOBRYCHIS VICIIFOLIA)

Two 2-arylbenzofurans have been isolated as insect feeding deterrents from the roots of the forage legume, sainfoin.They have been identified as 2-(2'-hydroxy-4'-methoxyphenyl)-5-hydroxy-6-methoxybenzofuran (sainfuran) and 2-(2',4'-dimethoxyphenyl)-5-hydroxy-6-methoxybenzofuran (methylsainfuran).Their synthesis is described. - Keywords: Onobrychis viciifolia; Leguminosae; sainfoin; 2-arylbenzofuran; sainfuran; methylsainfuran; antifungal activity; insect feeding deterrent; Costelytra zealandica.
