A Novel Method for Synthesis of Substituted Naphthofurans and Naphthopyrans
Abstract
Substituted naphthofurans and naphthopyrans were constructed at high temperature from allyl or propargyl naphthyl ethers via Claisen rearrangement in moderate to good yields. Also, substituted (trimethylsilyl)-naphthofurans were synthesized from the corresponding naphtofurans.
