[3+2]-Cycloadditions of Azomethine Imines and Ynolates and Progress Towards a Radical Three-Component Cross-Coupling Reaction
… [2+2]-annulation/fragmentation to construct cyclohexanones. Among all the methods to synthesize highly substituted cyclohexanols/cyclohexanones, there is no general, one-step enantioselective, intermolecular method to synthesize a highly substituted cyclohexanol/cyclohexanone with a …

Synthesis of delta-1(9)-octalinols and their analogues
… of the α, β unsaturated octalones obtained from cyclohexanones condensed with α, β -unsaturated ketones. These octalinols were characterised as their acetates (1, R=Ac). The attempts to convert these to the desired ketone dienes 2 by reaction with mixtures of acetic anhydride-acetic acid-boron …

DERIVATIVES OF 2-BENZYLIDENECYCLOHEXANONE AS POTENTIAL ANTINEOPLASTIC AGENTS
… the preparation of substituted (E)-2- benzylidenecyclohexanones, which are α,ß-unsaturated ketones, a class of compounds known to have alkylating properties. Only the substituted (E,E)-2,6-bis-(dichlorobenzylidene)cyclohexanones were isolated in the syntheses designed to yield …

The importance of the antiperiplanar effect in the nucleophilic addition of hydride to a carbonyl group.
… the calculations revealed, unlike 2-substituted cyclohexanones, only one energy minimum. The $\alpha$-fluoro derivative of our bridge biaryl ketone exhibits an extremely large preference for the equatorial conformation. However, for the $\alpha$-methylthio derivative of 44, the axial diastereomer …

Design and synthesis of novel non peptidomimtic beta-secretase inhibitors in the treatment of Alzheimer's disease
… The enantioenriched obtained 3-(α-nitroalkyl)-cyclohexanones were further functionalized to give the corresponding δ-nitroalkyl cyclohexane carboxylic acids. These intermediates were elaborated to the target structures 3-(α-aminoalkyl)-1-cyclohexane carboxylic acids in a new readily …
