Electrophilically activated nitroalkanes in the synthesis of substituted 1,3,4-oxadiazoles from amino acid derivatives

Novel preparative approach for the synthesis of alkylamines with 1,3,4-oxadiazole heterocyclic substituent is described. This method is based on unusual cascade transformation involving formal (4+1) cyclocondensation of hydrazides of amino acids with nitroalkanes electrophilically activated in the p...

Sammanfattning:	Novel preparative approach for the synthesis of alkylamines with 1,3,4-oxadiazole heterocyclic substituent is described. This method is based on unusual cascade transformation involving formal (4+1) cyclocondensation of hydrazides of amino acids with nitroalkanes electrophilically activated in the presence of polyphosphoric acid.
