General procedure.
General procedure: A typical reaction mixturecontaining 1a-1i (4 mmol), 2 (7.2 mmol), and 2 mLH2O was stirred at 60°C for a certain time until reactioncompletion (by TLC). After cooling, a precipitateformed and was fi ltered off and washed with water.The crude product was purifi ed by recrystallizationfrom water. All products are known compounds. Theywere characterized by melting points, 1H and 13CNMR spectra, and HRMS, which were consistent withpublished data [23, 24].
