Synthesis of pterocarpan-type heterocycles via oxidative cycloadditions of phenols and electron-rich arenes

Oxidation of 4-alkoxyphenols or 4-methoxynaphthol with phenyl iodonium(bis)trifluoroacetate (PIFA) in the presence of electron rich 2H-chromenes or dihydronaphthalenes affords pterocarpans or 5-carbapterocarpans via a formal [3+2] cycloaddition process. A

Silver-catalyzed asymmetric synthesis of 2,3-dihydrobenzofurans: A new chiral synthesis of pterocarpans

2,3-Dihydrobenzofurans can be diastereoselectively prepared by condensation of aromatic aldehydes with 2,3-dihydrobenzoxasilepines under the catalysis of Ag1 complexes, and in the presence of a source of fluoride ion. The application of this st

Syntheses of Pterocarpans, I. - Synthesis of Both the Enantiomers of Pterocarpin

The first synthesis of (-)-pterocarpin (6) was achieved by resolving (+/-)-2, which in turn was prepared from a known isoflavone (1).Unnatural (+)-pterocarpin was also synthesized.
