Catalytic diazo decomposition of representative N-allylic-N- methyldiazoacetamides produced the corresponding intramolecular cyclopropanation products in good to excellent yields and with exceptional enantiocontrol. In the simplest case, with N-allyl-N-methyldiazoacetamide, catalysis by dirhodium(II) tetrakis[methyl 2-oxapyrrolidine-5(S)-carboxylate], Rh 2(5(S)-MEPY)4, achieved the highest yield and enantioselectivity (93% ee). Dirhodium(II) tetrakis[methyl 2-oxo-1-(3- phenylpropanoyl) imidazolidin-4(S)-carboxylate], Rh2(4S)-MPPIM) 4, was preferred for substituted N-allylic-N-methyldiazoacetamides from which 92-95% ee's were obtained in intramolecular cyclopropanation reactions (88-95% yields), even when the catalyst was employed in only 0.1 mol %. Competition with intramolecular dipolar cycloaddition was minimized with the use of Nmethyldiazoacetamides relative to N-tert-butyldiazoacetamides.

Abstract: A one-stage and facile method of synthesis of expensive methyl- and ethyl(allyl)amines, methyl- and ethyl(prop-2-ynyl)amines, and methyl- and ethyl(allyl)(3-phenylprop-2-ynyl)amines is developed. The synthesized amines present practical interest, because some (prop-2-ynyl)amines are used in the therapy cancer.

A series of novel push-push I and push-pull II carbene-stabilized complexes of phosphorus(V) fluorides bearing substituents with liquid-crystalline properties were synthesized by the oxidative addition of difluoroamines to phosphorus(III) halides. These octahedral complexes were characterized by NMR spectroscopy and X-ray analysis.
