The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: (1S,2S)-N1,N2-Bis(3,3-dimethylbutyl)-N1,N2-dimethylcyclohexane-1,2-diamine( cas:767291-67-8 ) is researched.COA of Formula: C20H42N2.Gu, Xiaoyu; Tang, Yan; Zhang, Xiang; Luo, Zinbin; Lu, Hongfei published the article 《Organocatalytic Knoevenagel condensation by chiral C2-symmetric tertiary diamines》 about this compound( cas:767291-67-8 ) in New Journal of Chemistry. Keywords: aldehyde malonate chiral diaminocyclohexane enantioselective Knoevenagel condensation organocatalyst; unsaturated diester stereoselective preparation dynamic kinetic resolution. Let’s learn more about this compound (cas:767291-67-8).
The efficient Knoevenagel condensation catalyzed by (1S,2S)-1,2-diaminocyclohexane derivatives is presented and investigated. Various aliphatic aldehydes undergo condensation with active methylene compounds to yield the corresponding products in high yields. α-Branched aldehydes were found to be efficiently converted to the corresponding enantiomerically enriched products by using these chiral tertiary diamine catalysts.
