Addition of isobutyraldehyde to 1,2-bis(2-hydroxyphenyl)-1,2-diaminoethane (mother diamine) cleanly gives a stable, fused imidazolidine-dihydro-1,3-oxazine ring complex. However, vigorous heating of the fused ring complex gives the diaza-Cope rearrangement product with excellent yield and stereoselectivity. A variety of alkyl aldehydes have been
The aim of the present study was to investigate the similarities and differences in the olfactory and visual processing of emotional stimuli in healthy subjects and in patients with major depressive disorder (MDD). Twenty-five inpatients were investigated after admission to
Dioxygen epoxidation of cyclic alkenes into their corresponding epoxides was successfully achieved in good yield by using a novel binuclear manganese carboxamide complex as the catalyst and isobutyraldehyde as the cosubstrate.

The formation and catalytic behavior of active structures in a SiO(2)-supported unsaturated Ru complex catalyst for alkene epoxidation were studied by means of hybrid density functional theory (DFT) calculations. An energy-gaining route for the catalyst activation was found to allow
Organocatalytic enantioselective cross-aldol reactions of aldehydes with isatins: formation of two contiguous quaternary centered 3-substituted 3-hydroxyindol-2-ones.
