A hybrid transition-metal/radical process is described that results in the addition of organozinc reagents and alkyl halides across alkenyl boron reagents in an enantioselective catalytic fashion. The reaction can be accomplished both intermolecularly and intramolecularly, providing useful product yields and high enantioselectivities in both manifolds.

Research on the selectivity of etherlfication reactions of diols and esterification reactions of diacids by alkyl halides underphase-transfer catalysis has shown that under such conditions, selectivity of monoetherification increases in the order prim < sec < tert diols, though overall yield of monoether decreases from sec to tert diols. Monoesterification of diacids was accomplished with a high degree

Various alcohol silyl ethers were readily and efficiently transformed into the corresponding alkyl ethers in high yields by the use of aldehydes combined with triethylsilane in the presence of a catalytic amount of iron(III) chloride.
Active site plasticity of a critical enzyme from Mycobacterium tuberculosis

3-Deoxy-D-arabino-heptulosonate 7-phosphate synthase is an important biosynthetic enzyme in Mycobacterium tuberculosis and a potential drug target. We describe the synthesis, evaluation and docking of inhibitors with various chain lengths, which provide insight into the plasticity of the activesite for inhibitor binding.
