Compounds which are useful as inhibitors of cholesterol biosynthesis and thus as hypocholesterolemic agents are provided which have a quinoline or a pyridine anchor attached by means of a linker to a binding domain sidechain, which compounds inhibit the enzyme 3-hydroxy-3-methylglutaryl-coenzyme A reductase.
A new strategy has been established for the kineticresolution of racemic allylic alcohols through a palladium/sulfonyl‐hydrazide‐catalyzed asymmetric OH‐substitution under mild conditions. In the presence of 1 mol % [Pd(allyl)Cl]2, 4 mol % (S)‐SegPhos, and 10 mol % 2,5‐dichlorobenzenesulfonyl hydrazide, a range of racemic allylic alcohols were smoothly resolved with selectivity factors of more than

Methods of producing carboxylic acid ester derivatives of formulae (I) and (II), which are useful, for instance, as intermediates for producing an anti-hypercholesterolemic agent having an inhibitory effect on HMG-CoA Reductase: ##STR1## wherein R.sup.1 and R.sup.2 are independently a protective group for hydroxyl group, or R.sup.1 and R.sup.2 integrally constitute a protective group for hydroxyl groups; R.sup.3 is an alkyl group, or an aryl group; and R.sup.4 is a substituted aryl group, a substituted heterocyclic group, a substituted vinyl group, or a substituted cycloalkenyl group; and ##STR2## wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are respectively the same as defined in the above formula (I), are disclosed. In addition, intermediates for use in these methods of producing the carboxylic acid ester derivatives are disclosed.

Compounds which are useful as inhibitors of cholesterol biosynthesis and thus as hypocholesterolemic agents are provided which have the structure
wherein R is OH, or salts thereof or lower alkoxy;
Rx is H or alkyl;
R1 is lower alkyl;
R2 is lower alkyl;
R3 is phenyl or substituted phenyl; and
R4 is phenyl or substituted phenyl.
New pharmaceutical compositions containing such compounds especially oral dosage forms, and use of such compounds for the preparation of a pharmaceutical composition to inhibit cholesterol biosynthesis are also described.
