General description
(1R, 2R)-1,2-Bis(2-hydroxyphenyl)ethylenediamine or (R, R)-1,2-bis(2-hydroxyphenyl)-1,2-diaminoethane (HPEN) is commonly used in the stereoselective synthesis of enantiopure compounds.
Application
(1R, 2R)-1,2-Bis(2-hydroxyphenyl)ethylenediamine can be used as a precursor for the synthesis of:
- Enantiomerically pure trans-3-arylpiperazine-2-carboxylic acid derivatives via diaza-Cope rearrangement (DCR).
- 4,4′-(1,2-Diazaniumylethane-1,2-diyl)dibenzoate trihydrate by treating with terephthalaldehydic acid.
