摘要：

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 (+)-epsilon-viniferin, (+)-vitisin A and (-)-vitisin B, respectively, whose absolute configurations are known. (C) 1999 Elsevier Science Ltd.
