Asymmetric catalysis is an advanced area of chemical synthesis, but the handling of
abundantly available, purely aliphatic hydrocarbons has proven to be challenging. Typically …

We report a photochemical method for the semipinacol rearrangement of unactivated allylic
alcohols. Aliphatic as well as aromatic groups participate as migrating groups, yielding a …

Cyclopropanols have gained significant attention in organic synthesis as versatile three-
carbon synthons, as this readily available class of donor-activated cyclopropanes undergo …

A highly enantioselective cobalt‐catalyzed semipinacol rearrangement of symmetric α, α‐
diarylallylic alcohols is disclosed. A chiral cobalt‐salen catalyst generates a highly …

In this report, we describe a simple method for the synthesis of 2-aryl-2-vinyl-cyclobutanones
through the reaction of in situ generated cyclopropanones and cinnamylsulfonium ylides …

The catalytic asymmetric propargylation of enol (ate) intermediates is a well-established
method for the synthesis of α-propargyl-substituted carbonyl compounds. However, the …

A suite of internally functionalized Fe4L6 cage complexes has been synthesized with
lipophilic end groups to allow dissolution in varied solvent mixtures, and the scope of their …

The cyclopropylcarbinyl (CPC) and bicyclobutonium (BCB) structures of the C4H7+ cation
have been proposed as intermediates in various reactions forming cyclopropylcarbinyl …

Eine photochemische Methode für die Semipinakol‐Umlagerung von nichtaktivierten
Allylalkoholen wird beschrieben. Die Bedingungen erlauben die Umlagerung sowohl …

Significance: Jacobsen and co-workers disclose a protio-semipinacol ring expansion of vinyl
cyclopropanols into cyclobutanones bearing a quarternary stereogenic center in the …
