摘要

Cycloalkenones and a, a-disubstituted cycloalkanones were allowed to react under 15 kbar (1.5 GPa) preswre by employing either the protic conditions of ethylene glycol, triethyl orthoformate, and p-toluenesulfonic acid in benzene/toluene (73 mol ratio) at 40 OC for 48 h or the aprotic conditions of 1, 2-bis [(trimethylsilyl) oxy] ethane and TMSOTf in dichloromethane at 20" C for 24 h. Both the protic and aprotic high-pressure methods ...
