A short-step convenient synthesis of 2-phenylbenzofuran from 3-phenylcoumarin

The reaction mechanism of chemical conversion of (E)-β-[2-hydroxylphenylethylene]benzeneethanol into 2-phenylbenzofuran by DDQ, which involves loss of one carbon unit, was characterized and described. Five naturally occurring 2-phenylbenzofurans of not only the isoflavonoid but also stilbenoid origin were synthesized by use of this chemical scheme, which proved that this new scheme is a useful tool for quick synthesis of 2-phenylbenzofurans.

Diazo Compounds, 69. - 2-(or 4-)(Diazomethyl)-2-(or 4-)H-benzopyrans - Synthesis by Electrophilic Diazoalkane Substitution and Catalytic Decomposition

Electrophilic diazoalkane substitution of the (diazomethyl)phosphoryl compounds 9a-c with the benzopyrylium tetrafluoroborate 8 yields the 2--2H-1-benzopyrans 10a-c and the 4-isomers 11a-c.Lithiated methyl diazoacetate reacts anal

The Enamine Route to 2-Morpholinoisoflav-3-ene

In contrast to earlier reports, the condensation of N-styrylmorpholine with salicylaldehyde or with 3-methoxysalicylaldehyde gives 2-morpholinoisoflav-3-ene derivatives. 2-Morpholinoisoflav-3-ene can be hydrogenolysed in a useful synthesis of isoflavan; with acids it gives in high yield a remarkably stable di(isoflavenyl)ether (6); with triphenylmethyl perchlorate it gives isoflavylium perchlorate.A similar condensation with N-(cyclohexenyl)morpholine behaves differently, giving alcohols that are oxidised to chromone (or tetrahydroxanthone) derivatives, in accord withprevious reports.
