Highly Diastereo- and Enantioselective Allylboration of Aldehydes using alpha-Substituted Allyl/Crotyl Pinacol Boronic Esters via in Situ Generated Borinic Esters [PDF]

, 2013
Readily available, alpha-substituted allyl/crotyl pinacol boronic esters often give low E/Z selectivity (with Z favored) in reactions with aldehydes. We found that addition of nBuLi to the pinacol boronic ester followed by trapping of the alkoxide with ...

Catalytic borylation of methane [PDF]

Science, 2016
Methane borylation in a cyclohexane sea Although methane combusts readily at high temperatures, it is generally the hardest hydrocarbon to transform under gentler conditions, owing to its particularly strong C-H bonds. Cook et al.

Deprotonative C(sp3)/C(sp2)–H (Multi)Silylation of (Hetero)Arenes Mediated by NaTMP

Angewandte Chemie, EarlyView.
An operationally simple protocol using a strongly basic sodium amide in combination with sterically emcumbered silicon electrophiles enables the deprotonative C–H (multi)silylation of a myriad of (hetero)arenes. Mechanistic investigations highlight the pivotal role of steric and coordination effects in controlling the regioselectivity and efficiency of

BNB/NBN‐Phenalenyl‐2'‐deoxyuridines as a Fluorophore–Quencher Pair in DNA

Angewandte Chemie, EarlyView.
Two BN‐chromophore‐extended nucleosides containing electronically complementary BNB‐ and NBN‐doped phenalenyls were synthesised and incorporated into deoxyribonucleic acid (DNA) oligonucleotides. These chromophores act as an efficient fluorophore–quencher pair under aqueous conditions.
