4-Biarylyl-1-phenylazetidin-2-ones useful for the treatment of hypercholesterolemia are disclosed. The compounds are of a general formula (I) in which formula (II) represents an aryl or heteroaryl residue, Ar represents an aryl residue; U is a two to six atom chain; and the R’s represent substituents.
This invention provides cholesterol absorption inhibitors of Formula I:
and the pharmaceutically acceptable salts thereof, wherein R

is an alkyl, alkeny or alkynyl group mono- or poly-substituted with —OH, —COOH or a combination of —OH and —COOH, and R
9
contains an alkyl, alkeny or alkynyl group substituted with a heterocyclic ring, amino or sulfonyl. The compounds are useful for lowering plasma cholesterol levels, particularly LDL cholesterol, and for treating atherosclerosis and preventing atherosclerotic disease events.
K<sub>2</sub>S<sub>2</sub>O<sub>8</sub>-Mediated Selective Trifluoromethylacylation and Trifluoromethylarylation of Alkenes under Transition-Metal-Free Conditions: Synthetic Scope and Mechanistic Studies
on and -arylation of alkenes with inexpensive CF3SO2Na and K2S2O8 in aqueous media has been developed, respectively, affording the highly chemoselective synthesis of CF3-functionalized chroman-4-ones and chromanes in satisfactory yields. Control experiments and DFT calculations indicate that the CF3SO2Na/K2S2O8 system is capable of trifluoromethylating the substrate of alkenes without a transition

‐Butyl Hydroperoxide‐Initiated Radical Cyclization of 1‐(Allyloxy)‐2‐(1‐Arylvinyl)Benzenes with Sulfinic Acids to Access Sulfonated Benzoxepines
A tert-butyl hydroperoxide-initiated radical cyclization of 1-(allyloxy)-2-(1-arylvinyl)benzenes with sulfinic acids for the construction of sulfonated benzoxepines is developed. This reaction involves a radical pathway and offers a straightforward route to the formation of seven-memberedring via sulfonylation/cyclization process. This methodology features mild reaction conditions, a broad substrate
