Hypervalent iodine reagents are in high current demand due to their exceptional reactivity in
oxidative transformations, as well as in diverse umpolung functionalization reactions. Cyclic …

Abstract The Meyer–Schuster rearrangement of propargylic alcohols is a transformation in
organic synthesis known for almost a century. The products of this reaction—α, β‐enones …

Abstract The Meyer‐Schuster rearrangement is an efficient method to prepare α, β‐
unsatured carbonyl compounds starting from propargylic alcohols and this review presents …

A general method for isoxazoles from readily available ynones using trimethylsilyl azide as
an amino surrogate, likely via an unprecedented hydroazidation of the alkyne and …

Herein we present a new unified concept for C− C bond formation under redox‐neutral
conditions. Our strategy hinges upon interception of a vinyl cation with a sulfoxide resulting …

Conspectus Enolate chemistry is one of the most fundamental strategies for the formation of
carbon–carbon and carbon–heteroatom bonds. Classically, this has been accomplished …

Conjugated enynes, enol ethers, and enynones are versatile building blocks that can be
elaborated by a wide variety of synthetic transformations. The selective synthesis of such …

We describe a mild and broadly applicable protocol for the preparation of a diverse array of
multisubstituted α-selenoenals and-enones from readily accessible propargylic alcohols and …

Addition of arylboronic acids to directing group tethered acetylenes in a regio and
stereoselective manner using an inexpensive catalytic system is achieved for the first time to …

Benziodoxole triflate (BXT), a cyclic iodine (III) electrophile, has been found to promote a
rearrangement of propargylic alcohols into α, β-unsaturated ketones bearing an α-λ3 …
