Given the widespread importance of piperazines as building blocks for the production of pharmaceuticals, an efficient and selective synthesis is highly desirable. Here we show the direct synthesis of piperazines from 1,2-dicarbonyl and 1,2-diamine substrates using the R-selective imine reductase from Myxococcus stipitatus as biocatalyst. Various N- and C-substituted piperazines with high activity and excellent enantioselectivity were obtained under mild reaction conditions reaching up to 8.1 g per liter.

The synthesis and diuretic activity were reported of a series of N1-(4-chloro-3-sulfamoylbenzamide)-N4-alkylpiperazines, 2-methyl- and cis-2,6-dimethyl substituted, structurally related to clopamide, as well as of two N4-alkyl-N1-(4-chloro-3-sulfamoylbenz

A series of substituted 2,4-dimethylpiperazines (10-15), 1-benzyl-2-methylpiperazines (16-19), 1-substituted 3-methylpiperazines (20-25,27) and 1,4-disubstituted piperazines (28-34) have been synthesized starting from 1-benzyl-2-methylpiperazine (9) and 1
