Chemical Research Letters, May 2021. The appropriate choice of redox mediator can avoid electrode passivation and overpotential, which strongly inhibit the efficient activation of substrates in electrolysis. SDS of cas: 107-97-1,107-97-1, Name is Sarcosine, SMILES is C(C(=O)O)NC, belongs to pyrrolines compound. In a document, author is Ricko, Sebastijan, introduce the new discover.
Construction of Vicinal Tetrasubstituted Stereogenic Centers via a Mannich-Type Organocatalyzed Addition of Delta(2)-Pyrrolin-4-ones to Isatin Imines
Racemic (2)-pyrrolin-4-ones (i.e. 4-pyrrolones), easily available in two steps from N-protected -amino acids, undergo organocatalysed asymmetric Mannich-type addition to isatin-derived ketimines to furnish the non-racemic oxindole-(2)-pyrrolin-4-one adducts, stereoselectively (up to 96% ee, dr15:1). The oxindole-pyrrolone products feature vicinal tetrasubstituted carbon stereocenters. The developed protocol has a broad substrate scope and tolerates diverse substituents at position C-5 in 4-pyrrolones and at positions N-1 and C-5/7 in isatin imines.
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. you can also check out more blogs about 107-97-1. SDS of cas: 107-97-1.
