Synthesis of benzofurans and benzopyrans

, 2002
Syntheses of 2,3-dihydrobenzofurans and 3,4-dihydrobenzopyrans normally involve several stages, therefore efficient syntheses of these compounds are desirable. A number of 3,4-dihydrobenzopyrans derivatives were prepared in one pot syntheses. The reaction is thought to proceed through cation intermediates, involving allylic cations generated by the ...
