preparation of a range of N-substituted phosphoramidohydrazides, hydrazones, and azides is described. NN′-Dibenzylphosphorodiamidic azide is comparatively stable: at 180–200° pyrolysis occurred to give a mixture of products; in boiling decane NN′-dibenzylphosphenimidic amide was formed; the latter also resulted from attempted insertion reactions with boiling o-xylene and piperidine. The azide was unchanged by
Enantioselective Synthesis of Quaternary Carbon Stereogenic Centers through the Primary Amine-Catalyzed Michael Addition Reaction of α-Substituted Cyclic Ketones at High Pressure
The enantioselectiveMichaeladditionreaction of α-substitutedcyclicketones with acrylates was efficiently promoted by a primary amine chiral catalyst under high-pressure conditions (1.0 GPa) in tetrahydrofuran. This method was highly successful for the construction of an all-carbon-substituted quaternary-carbon stereogeniccenter at the α-position of cyclicketones in high enantiomeric excess,
Halides-based electrophiles mediated epoxide ring-opening reactions of α,β-epoxysulfoxides in C6-series : Deoxygenation versus dehydration and an overall 1,2-keto transposition
several halides-based electrophiles are described. Mechanistic considerations for deoxygenation as well as dehydration reactions are also discussed. In addition, methodology for achieving 1,2-carbonyltransposition starting with isomerically pure cyclohexenyl sulfides derived from isophorone and cholestan-3-one is briefly reported.
REGIOCHEMICAL CONTROL IN THE 1,2-CARBONYL TRANSPOSITION OF α,α′-DIMETHYLENE SYSTEMS THROUGH REGIOSELECTIVE SULFENYLATION OF TOSYLHYDRAZONE DIANIONS

The regiochemical outcomes are described in the 1,2-carbonyl shift of α,α′-dimethylene systems which relies upon the regioselective sulfenylation of tosylhydrazone dianions leading to the enol thioethers of transposed ketones. Notably, a high regiospecificity was obtained with β-methyl- and β,β-dimethylcyclohexanone without any attempts to separate the stereoisomers of the hydrazones.
