    • 2 cycles, the tube was pressurized to an initial pressure of 2 atm. The tube was closed off and the mixture was stirred at ambient temperature. After stirring for 3-18 h, the mixture was passed through a silica gel column with eluting EtOAc, and the filtrate was concentrated under reduced pressure. The residue was subjected to HPLC analysis
