Yield: 82%
Reaction Conditions:
with [bis(acetoxy)iodo]benzene in dichloromethane for 2 h;Reflux;
Steps:
Ethyl 2-thienylglyoxylate 3m
General procedure: β-Oxo-benzenepropanenitrile 1(1.0 mmol),PIDA (2.2 mmol) were dissolved in EtOH (8 mL) and stirred under refluxing for 0.5h. After the reaction was completed (monitored by TLC), thereaction mixture was concentrated under vacuum. The residue was purified by chromatographyon silica gel (20:1 petroleum ether/EtOAc) to give the product 3a-o .Thesolvent for the synthesis of 3o was MeOH.
