1. INTRODUCTION The focus of this review is on the reactivity of cationic, tricoordinated
boron electrophiles and on recent applications that rely on intermediates having sextet …

Here we report an iridium-catalyzed asymmetric umpolung allylation of imines as a general
approach to prepare 1, 4-disubstituted homoallylic amines, a fundamental class of …

Allylboration of ketones with γ-disubstituted allylboronic acids is performed in the presence
of chiral BINOL derivatives. The reaction is suitable for single-step creation of adjacent …

The development of α, α-disubstituted crotylboronate reagents is reported. Chiral Brønsted
acid-catalyzed asymmetric aldehyde addition with the developed E-crotylboron reagent …

Readily available, α-substituted allyl/crotyl pinacol boronic esters often give low E/Z
selectivity (with Z favored) in reactions with aldehydes. We found that addition of n BuLi to …

Chiral secondary allylboronates are obtained in high enantioselectivities and 1, 6: 1, 4 ratios
by the copper‐catalyzed 1, 6‐boration of electron‐deficient dienes with bis (pinacolato) …

A growing world population and increasing energy demands are without a doubt the most
important challenges for mankind within this century. Catalysis is a key technology in various …

We have developed a stereospecific, nickel-catalyzed Miyaura borylation of allylic pivalates,
which delivers highly enantioenriched α-stereogenic γ-aryl allylboronates with good yields …

The Matteson homologation with vinyl nucleophiles was found to be a versatile tool for the
synthesis of highly substituted and functionalized allyl boronic esters. High yields and …
