The reaction of RhCl(PPh3)3 with Et2Zn easily generated a rhodium-hydride complex (Rh-H) that added to α,β-unsaturated esters to form rhodium enolate complexes by formal 1,4-reduction. These rhodium enolates gave the corre

The reaction of S-tert-butyl thiopropionate with a number of N-benzyl or N-allyl aldimines (4) as promoted by the chiral diazaborolidine 1 and triethylamine afforded the β-amino acid esters 5 with high diastereoselectivity and enantioselectivity, providin
STANNOUS TRIFLATE MEDIATED ALDOL REACTION OF 3-ACYLTHIAZOLIDINE-2-THIONE: A CONVENIENT METHOD FOR THE STEREOSELECTIVE SYNTHESIS OF β-HYDROXY ALDEHYDE AND β-HYDROXY CARBOXYLIC ACID DERIVATIVES

Divalent tin enolates, formed from stannous triflate and 3-acylthiazolidine-2-thiones, react with aldehydes with erythro-selectivities.The adducts are easily transformed into β-hydroxy aldehyde and β-hydroxy carboxylic acid derivatives.
STEREOSELECTIVE REDUCTION OF β-KETO ESTERS WITH ZINC BOROHYDRIDE. STEROSELECTIVE SYNTHESIS OF ERYTHRO-3-HYDROXY-2-ALKYLPROPIONATES
Nakata, Tadashi,Oishi, Takeshi
, p. 1641 - 1644 (2007/10/02)
Erythro-3-hydroxy-2-alkylpropionates were prepared in high stereoselectivity and in high isolated yield by zinc borohydride reduction of the corresponding β-keto esters.
