Synthesis and properties of 4-chloromethyl-6-hydroxycoumarins and 4-(2-benzofuryl)-6-hydroxycoumarins

Abstract

New 4-chloromethyl-6-hydroxycoumarins have been obtained by the condensation of hydroquinone derivatives with 4-chloroacetoacetic ester, and have been used for the synthesis of 4-(2-benzofuryl)-6-hydroxycoumarins. Alkylation and acylation of the phenolic hydroxyl of the synthesized 4-(2-benzofuryl)coumarins have been investigated.
