The first total synthesis of the antiviral flavonoid houttuynoid A (1) has been achieved from aryl ketone 6 and benzofuran aldehyde 5 in nine linear steps. The C6–C3–C6 structure of the flavonoid was synthesized by an I2-catalyzed oxa-Michael addition of a chalcone intermediate, generated by the Claisen–Schmidt condensation of 5 and 6. This work provides a method for the synthesis of houttuynoids and
抗病毒类黄酮类胡芦巴素类化合物A(1)的第一个全合成是在9个线性步骤中从芳基酮6和苯并呋喃醛5实现的。类黄酮的C 6 –C 3 –C 6结构是通过I 2催化的查尔酮中间体的氧杂-迈克尔加成反应合成的,该查尔酮中间体是由5和6的Claisen-Schmidt缩合反应生成的。这项工作提供了一种合成类胡桃突的方法,并为合成类胡桃突家族的其余成员提供了参考。
