The photoredox-catalyzed α-aminoalkylcarboxylation of aryl allenes with CO2 and N,N-dimethylanilines is reported for the first time (26 examples, up to 96% yield). In the case of electron-deficient allenes, good regioselectivity was observed (up to 94:6), exclusively generating kinetic products over thermodynamic products. This protocol is a novel synthetic method for highly functionalized β,γ-unsaturated γ-aminobutyric esters.

A highly regioselective iodosulfonylation of allenes in the presence of CuI and 1,10-phenanthroline has been developed for the synthesis of various useful (E)-α-iodomethyl vinylsulfones in moderate to excellent yields. This practical reaction is fast, operationally simple, and in particular, proceeds under very mild conditions to afford the target products with high regio- and stereoselectivity. The selectivity was illustrated by a conceptual DFT analysis.
Carbon-13 Nuclear Magnetic Resonance Spectroscopy of 1-Aryl-2,2-dibromocyclopropanes
Lin, Shaw-Tao,Lin, Mei-Ling
, p. 91 - 95 (2007/10/02)
The 13C NMR spectra of 12 1-aryl-2,2-dibromocyclopropanes have been measured and 1-phenyl-2,2-dibromocyclopropanes was studied under different conditions of concentration, solvent, and temperature.The results suggest that the field effect is mainly respon
