The synthesis of α-pyrazole and α-triazole derivatives of ketones by the ceric ammonium nitrate-mediated oxidative coupling of enolsilanes with heteroarenes is reported. The reaction proceeds under mild reaction conditions to provide a diversity of products, including sterically hindered fully substituted derivatives.

3-(1-imidazolyl)chroman-4-ones and 2-(1-imidazolyl)-1-tetralones II, some of their alcohols, and some relatedcompounds were synthesized and tested for hypolipidemic activity. CompoundsII, bearing appropriate lipophilic substituents on the phenyl ring, strongly reduced total serum cholesterol while raising high-density lipoprotein cholesterol in diet-induced hypercholesterolemic rats. 3-(1-Imidazolyl)chroman-4-ols
