Abstract

Results Treatment of ketones 3a-d and 6 (0.1 mol) with trimethylsilyl chloride (0.12 mol) and triethylamine (0.13 mol) in N, N-dimethylformamide (200 mL) at reflux temperature overnight afforded trimethylsilyl enol ethers 4a-d and 7, respectively, 21 and the reaction of ketone 9, esters 12a-c, and e-caprolactone (15)(0.1 mol) with lithium diisopropylamide (0.1 mol) and trimethylsilyl chloride (0.12 mol) yielded trimethylsilyl enol ethers 13a-~,~~ and
