Synthetic Implications of Spin States in the Reactivity of Ni Intermediate Complexes in Coupling Reactions

European Journal of Organic Chemistry, EarlyView.
The formation of triplet Ni(II) complexes by activation of bromoalkenes with alkyl‐ or boryl Ni(I) is key to control the outcome of the reductive cross‐coupling of bromoalkanes precluding the formation of alkylboronates. We present a mechanistic study on the Ni‐catalyzed cross‐coupling reaction of bromoalkanes with diboron compounds as reductants.

Silyl Rearrangements in Gold‐Catalyzed Transformations

European Journal of Organic Chemistry, EarlyView.
The synergy between the exceptional ability of gold catalysts to activate unsaturated substrates and the inherent tendency of organosilicon reagents to undergo silyl‐group rearrangements has unlocked a range of novel transformations, enabling access to otherwise challenging molecular architectures.

Stereoselective Chemoenzymatic Synthesis Metaraminol Involving Gold‐Catalysed Alkyne Hydration and Carbonyl Biotransamination

European Journal of Organic Chemistry, EarlyView.
A chemoenzymatic synthesis of (1R,2S)‐metaraminol was developed by combining gold(I)‐catalysed alkyne hydration and stereoselective biotransamination in a sequential one‐pot process. Various phenol protection strategies were considered in oxidation‐reduction sequences, providing access to enantiopure propargylic alcohols as starting materials for ...
