Epoxide rearrangements using dilithiated aminoalcohols as chiral bases

, 2002
Dilithiated norephedrine and ephedrine have been utilised in the enantioselective rearrangement of cyclic epoxides to allylic alcohols, with dilithiated norephedrine generally giving the best enantioselectivity.

Synthesis and testing the cardiocirculatory effects of N-(3'-methoxybenzamidomethyl)-D-norephedrine and analogous compounds

, 1976
Twenty-six substituted N-benzamidomethyl and 3 N-(diphenylacetamido)methyl amines were prepd. by coupling I groups (R1 = H or MeO; R2 = H, Me MeO, EtO, PrO, or Cl; R3 = H, MeO, or Cl) and Ph2CHCONHCH2 groups, resp., to the N atom of phenylethylamine ...

Immobilization of chiral amide derived from (1R,2S)-(-)-norephedrine over 3D nanoporous silica for the enantioselective addition of diethylzinc to aldehydes

, 2012
Chiral amide synthesized from (1R,2S)-(-)-norephedrine has been successfully immobilized onto three dimensional Ia3d cubic nanoporous material. The immobilization of the chiral amide has been confirmed by using various physiochemical techniques.
