Asymmetric Approach toward Chiral Cyclohex-2-enones from Anisoles via an Enantioselective Isomerization by a New Chiral Diamine Catalyst

, 2016
A 3-step asymmetric approach toward the optically active chiral cyclohex-2-enones from anisoles has been developed. The crucial asymmetric induction step is an unprecedented catalytic enantioselective isomerization of β,γ-unsaturated cyclohex-3-en-1-ones

Ammonium-directed dihydroxylation: metal-free synthesis of the diastereoisomers of 3-aminocyclohexane-1,2-diol.

, 2008
The ammonium-directed, metal-free oxidation of 3-(N,N-dibenzylamino)cyclohex-1-ene with mCPBA in the presence of either trichloroacetic acid or tosic acid has been used as the key step to facilitate the synthesis of all the diastereoisomers of 3 ...

N‑Heterocyclic Carbene-Catalyzed α,β-Unsaturated Aldehydes Umpolung in Fullerene Chemistry: Construction of [60]Fullerene-Fused Cyclopentan-1-ones and Cyclohex-2-en-1-ones

, 2018
The first umpolung strategy for the cycloacylation of fullerene using a N-heterocyclic carbene organocatalyst is reported. The coupling of [60]­fullerene with different structural α,β-unsaturated aldehydes efficiently furnishes interesting [60]­fullerene-

The mechanism of oxidation of allylic alcohols to alpha,beta-unsaturated ketones by cytochrome p450

, 1996
The oxidation of cyclohex-2-en-l-ol, a simple model substrate for allylic alcohols, is catalyzed by several P450 isoenzymes and leads exclusively to cyclohex-2-en-1-one, No double bond epoxidation or C(4) hydroxylation have been observed.
