Organocatalytic enantioselective Mannich-type reaction of phosphorus ylides: Synthesis of chiral N-Boc-beta-amino-alpha-methylene carboxylic esters
The first asymmetric Mannich-type reaction of stabilized phosphorus ylides and N-Boc aldimines was described promoted by a readily available and recyclable chiral bisthiourea organocatalyst. Subsequent reaction with formalin smoothly provides N-Boc-beta-amino-alpha-methylene carboxylic esters in a highly enantiomerically enriched form (up to 96% ee). Copyright
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: Tetrafluorophthalic anhydride, you can also check out more blogs about652-12-0
