中文摘要：

苯并吡喃骨架存在于许多天然及合成的生物活性物质中，因此发展其高效合成方法极具实用价值.本工作以氯化锌为催化剂催化酚与异戊烯基溴发生傅克/氢烷氧化串联反应，高效合成了一系列苯并吡喃化合物.该方法所用催化剂简单易得，催化剂用量少，反应条件温和，为苯并吡喃类化合物的合成提供了一种高效且实用的路径.

英文摘要：

Chroman skeleton exists in many natural and synthetic biologically active materials. A highly efficient method for the synthesis of chromans via reaction of phenols with prenyl bromide catalyzed by zinc chloride is described, which provides a practical process to afford this type of biologically important compounds in good yields using commercially available and inexpensive catalyst under mild conditions.
