Diastereoselective Alkene Hydroesterification Enabling the Synthesis of Chiral Fused Bicyclic Lactones

Palladium-catalysed diastereoselective hydroesterification of alkenes assisted by the coordinative hydroxyl group in the substrate afforded a variety of chiral γ-butyrolactones bearing two stereocenters. Employing the carbonylation-lactonization products as the key intermediates, the route from the alkenes with single chiral center to chiral THF-fused bicyclic γ-lactones containing three stereocenters was developed.

Tricyclic compound derivatives useful in the treatment of neoplastic diseases, inflammatory disorders and immunomodulatory disorders

Provided are compounds of the formula (I): or a stereoisomer, tautomer, salt, hydrate or prodrug thereof that modulate tyrosine kinase activity, compositions comprising the compounds and methods of their use.

Pyrrolidinyl and pyrrolinyl ethylamine compounds as kappa agonists

A compound of the following formula: and the salts thereof wherein A is hydrogen, halo, or hydroxy, broken line represents an optional double bond with proviso that if the broken line is a double bond, then A is absent; Ar1is optionally substituted phenyl; Ar2is aryl or heteroaryl selected from phenyl, napththyl, or pyridyl, the aryl or heteroaryl being optionally substituted; R1is hydrogen, hydroxy, or C1-C4alkyl; and R2and R3are independently selected from optionally substituted C1-C7alkyl, C3-C6cycloalkyl, C2-C6alkenyl, C2-C6alkynyl, or R2and R3, together with the nitrogen atom to which they are attached, form an optionally substituted pyrrolidine. These compounds are useful as kappa agonists.

Convenient synthesis of optically active 1,2-diol monosulfonates and terminal epoxides via oxazaborolidine-catalyzed asymmetric borane reduction of α-sulfonyloxy ketones

A very convenient asymmetric synthesis of 1,2-diol monosulfonates and terminal epoxides with high optical purity via oxazaborolidine-catalyzed asymmetric borane reduction of α-sulfonyloxy ketones using N-ethyl-N-isopropylaniline-borane complex as borane carrier has been developed.
