Ethylenediamine (H2NCH2CH2NH2) was found to be a highlyeffectivecatalyst for the condensation of aryl aldehydes with nitromethane (or nitroethane). When 1%–2% (mol%) of ethylenediamine was used as the catalyst, the one‐pot reaction of aryl aldehydes with nitromethane (or nitroethane) by refluxing for 3–10 h efficiently afforded various arylnitroalkenes 1a–1y in 85%–97% yields.

日期:——
The first highly chemo- and enantioselective hydrogenation of α,β-disubstituted nitroalkenes was accomplished with rhodium/JosiPhos-J2 as a catalyst, with the yield and enantioselectivity of up to 95% and 94%, respectively. The α-chiral nitroalkanes will provide an entry to valuable chiral amphetamines which are otherwise not so easily accessed.
