neolignans. This research reports the successful asymmetric synthesis of both a 9-hydroxy-5′-methoxy-1,4-benzodioxane framework and a highly functionalised benzofuran scaffold. Both synthetically desirable structures are the result of a Lewis acid catalysed addition of an aryl nucleophile to 1,4-benzodioxane hemiacetals and offer a route towards the synthesis of a number of naturally occurring neolignans.
摘要 这项研究报告了9-羟基-5'-甲氧基-1,4-苯并二恶烷骨架和高度官能化的苯并呋喃支架的成功不对称合成。两种合成上所需的结构都是路易斯酸催化的芳基亲核试剂与1,4-苯并二恶烷半缩醛加成的结果,并为合成许多天然存在的新木脂素提供了一条途径。 这项研究报告了9-羟基-5'-甲氧基-1,4-苯并二恶烷骨架和高度官能化的苯并呋喃支架的成功不对称合成。两种合成上所需的结构都是路易斯酸催化的芳基亲核试剂与1,4-苯并二恶烷半缩醛加成的结果,并为合成许多天然存在的新木脂素提供了一条途径。
