Routes were investigated for the synthesis of cicerfuran, a hydroxylated benzofuran from wild chickpea implicated in resistance to Fusarium wilt, and some of its analogues. A novel method is described for the synthesis of oxygenated benzofurans by epoxidation and cyclisation of 2′-hydroxystilbenes. The stilbene intermediates required could be synthesised by palladium-catalysed coupling of styrenes
研究了从野生鹰嘴豆中合成羟基化的苯并呋喃类化合物cicerfuran的途径,其中涉及抗枯萎病枯萎病及其一些类似物。描述了一种新的方法,用于通过2'-羟基苯乙烯的环氧化和环化合成氧化的苯并呋喃。所需的二苯乙烯中间体可以通过钯催化的苯乙烯与单加氧的芳基卤化物而不是与二加氧的芳基卤化物偶合而合成。通过维蒂希反应合成了对应于后者的二苯乙烯。
