Construction of highly functionalized thiophene and benzo[b]thiophene derivatives via a sequence of propargyl–allenyl isomerization/cyclization/demethylation
An efficient one-pot protocol for the synthesis of functionalized thiophene and benzo[b]thiophene derivatives was developed via a sequence of propargyl–allenyl isomerization/cyclization/demethylation. As a result of the readily accessible starting materials, simple operation, and mild conditions, this reaction should have potential utility in organic synthesis.
