Steps:

2.3.2. General procedure for the synthesis of compounds3a-3e from compounds 2a-2e

General procedure: The synthetic procedure of compounds 3a-3e: To a stirredsolution of 2a-2e (20 mmol) in EtOH (40 mL) and was addedethyl 2-chloro-3-oxobutanoate (20 mmol, 3.29 g), the reactionmixture was heated at reflux in N2 atmosphere until the completion of reaction as indicated by TLC analysis (typicallywithin 5 h).The reaction mixture was poured into ice-water (100 mL)and the mixture thus obtained was extracted with CH2Cl2(100 mL 3). The combined organic phases were washedwith saturated brine (300 mL), dried over anhydrous Na2SO4and evaporated on a rotary evaporator to afford a residue,which was purified by column chromatography through ashort silica gel column to yield 3a-3e.
