Ni-Catalyzed Reductive Allylation of α-Chloroboronates to Access Homoallylic Boronates

The transition-metal-catalyzed allylation reaction is an efficient strategy for the construction of new carbon-carbon bonds alongside allyl or homoallylic functionalization. Herein we describe a Ni-catalyzed reductive allylation of α-chloroboronates to efficiently render the corresponding homoallylic boronates, which could be readily converted into valuable homoallylic alcohols or amines or 1,4-diboronates. This reaction features a broad substrate scope with good functional group compatibility that is complementary to the existing methods for the preparation of homoallylic boronates.

Iridium-catalyzed chemoselective and enantioselective hydrogenation of (1-Chloro-1-Alkenyl) boronic esters

Persistent chlorine: Hydrogenation of borolane-substituted vinylic chlorides catalyzed by Ir-P N complexes greatly preserved the chlorine substituent on the hydrogenated product, with only 3-19 % of dechlorinated byproducts present after hydrogenation. Th

P1 Phenethyl peptide boronic acid inhibitors of HCV NS3 protease

A series of peptide boronic acids containing extended, hydrophobic P1 residues was prepared to probe the shallow, hydrophobic S1 region of HCV NS3 protease. The p-trifluoromethylphenethyl P1 substituent was identified as optimal with respect to inhibitor potency for NS3 and selectivity against elastase and chymotrypsin.

An α-lithio boronic ester from an α-trimethylstannyl boronic ester

Pinacol (1-chloroethyl)boronate (1A) and lithiotrimethylstannane have yielded pinacol [1-(trimethylstannyl)ethyl]boronate (2), which with methyllithium at -100C yields pinacol 1-lithioethylboronate (3). Capture of 3 by (-haloalkyl)boronic esters results in carbon-carbon bond formation. Generation of 3 from pinacol (1-iodoethyl)boronate with tert-butyllithium is followed by rapid reaction with the remaining (1-iodoethyl)boronate.
