Simple and Convenient Synthesis of 4‐Unsubstituted‐3‐(3‐Oxoalkyl)isocoumarins
摘要:
A simple transformation of 2-alkylfurans and 2-formylbenzoic acids into 4-unsubstituted 3-(3-oxoalkyl)isocoumarins is described. It is based on the synthesis of 2-(2-carboxybenzyl)furans followed by their acid-catalyzed recyclization to the target isocoumarins.
