catalytic enantioselective method for the synthesis of 1,4-keto-alkenylboronate esters by a rhodium-catalyzed conjugate addition pathway is disclosed. A variety of novel, bench-stable alkenyl gem-diboronate esters are synthesized. These easily accessible reagents react smoothly with a collection of cyclic α,β-unsaturatedketones, generating a new C-C bond and stereocenter. Products are isolated in up to

Compounds which are useful as inhibitors of cholesterol biosynthesis and thus as hypocholesteroleumic agents are provided which have the structure ##STR1## wherein R is OH, or salts thereof or lower alkoxy; R.sup.x is H or alkyl; X is --CH.sub.2 --, --CH.sub.2 --CH.sub.2 --, --CH.dbd.CH--, --C.tbd.C--, --CH.sub.2 CH.sub.2 CH.sub.2 -- or --CH.sub.2 O-- (where O is linked to Z); Z is a hydrophobic anchor, such as ##STR2## wherein the dotted lines represent optional double bonds. New intermediates used in preparing the above compounds, pharmaceutical compositions containing such compounds and a method for using such compounds to inhibit cholesterol biosynthesis are also provided.

Compounds of the structure ##STR1## where p and q are zero or one, but cannot both be the same, M is a pharmaceutically acceptable cation or a metabolically cleavable group, B is a valence bond or a straight or branched alkylene group, R is alkyl, cycloalkyl or --NR.sup.1 R.sup.2, where R.sup.1 and R.sup.2 are hydrogen, alkyl, cycloalkyl or alkanoyl, and A is optionally substituted carbocyclic aryl, furyl, benzo[b]furyl, thienyl, or benzo[b]thienyl are potent inhibitors of lipoxygenase enzymes and thus inhibit the biosynthesis of leukotrienes. These compounds are useful in the treatment or amelioration of allergic and inflammatory disease states.
