o-Hydroxyaroylmethyltriarylphosphonium(arsonium) bromides and o-hydroxyaroylmethylenetriarylphosphoranes(arsoranes)
Preparation of o-hydroxyaroylmethyltriarylphosphonium(arsonium) bromides by reaction of substituted o-hydroxy-ω-bromoacetophenones with triarylphosphines(arsines) and their subsequent conversion into o-hydroxyaroylmethylenetriarylphosphoranes(arsoranes) o

Synthesis and hypolipidemic activity of novel 4-oxo- and 4-thioxo-4H-benzopyran-2-phenylalkanoic acids and esters
Novel 4-oxo- and 4-thioxo-4H-benzopyran-2-phenylalkanoic acids and esters have been prepared and evaluated for their hypolipidemic activity.Among these compounds 3'-alkanoyl derivatives show superior activity, decreasing total cholesterol, triglycerides a

New route to styrylchromones via [1-(2-hydroxybenzoyl)alkylidene]triphenylphosphoranes
Several [1-(2-hydroxybenzoyl)alkylidene]triphenylphosphoranes have been obtained in good yields through acylation of the corresponding alkylidenetriphenylphosphoranes, prepared in situ, by the easily available methyl 2-hydroxybenzoates. These ylides prove
