Abstract
Three new oligostilbenes having a benzofuran moiety, viniferifuran, (+)- vitisifuran A and (-)-vitisifuran B, were isolated from Vitis vinifera 'Kyohou'. The structures of these oligostilbenes including the absolute configuration were elucidated by spectroscopic and chemical methods. Furthermore, these were chemically transformed from (+)-ε-viniferin, (+)- vitisin A and (-)-vitisin B, respectively, whose absolute configurations are known.
