Addition to “Thianthrenation-Enabled Pyrrolidin-2-yl and . . . In order to diferentiate two possible syn- and anti-hetereopalladation pathways, two deuterated pent-4-en-1-ol 2d and 2e were employed for this carboalkoxylation (Scheme 1b) The obtained low diastereoselectivity in both deuterated alkenols suggests a mixed syn- and anti-hetereopalla-dation pathways in this reaction (Scheme 1c) 1
Recent developments in next generation (S)-proline-derived chiral . . . In particular, the design and evaluation of diamine analogs of privileged (S)-prolinols as organocatalysts is discussed Furthermore, the remarkable influence of solvate ionic liquids as well as the usage of other types of ionic liquids that results in a significant improvement of the catalytic activity of (S)-proline is described
Enantioselective organocatalytic aldol reaction using small organic . . . This review emphasizes asymmetric direct aldol reactions catalyzed by small enantioenriched organic molecules, particularly those involving enamine catalysis through primary and secondary amines We have made significant efforts to include several important contributions from different groups in this area 1 Introduction
Highly enantioselective epoxidation of olefins by H2O2 catalyzed by a . . . In a recent study, the effects of different side arms attached to the chiral (S, S)-2,2′-bispyrrolidine backbone on the Fe (ii)-catalyzed asymmetric epoxidation of olefins were investigated, and the study concluded that complexes containing (N -methyl)benzimidazole and electron rich pyridine or bulky pyridine resulted in excellent yields and ena
Novel Enantioselective Synthesis of Both Enantiomers of Furan‐2‐yl . . . A new enantioselective synthesis of furan‐2‐yl amines and amino acids is described, in which the key step is the oxazaborolidine‐catalyzed enantioselective reduction of O‐benzyl (E)‐ and (Z)‐furan‐2‐yl ketone oximes to the corresponding chiral amines
