, p. 698 - 707 (2007/10/03)
We have investigated a number of nucleophillic additions to L-erythrulose derivatives (4-12) bearing protective O-silyl, O-benzyl, and O-trityl groups in various relative positions. The results are discussed in the frame of chelated vs nonchelated transit
Diastereoselective Addition of Grignard Reagents to 3,4-O-Isopropylidene-1-O-triphenylmethyl-L-glycero-2-tetrulose and 1-O-Benzoyl-3,4-O-isopropylidene-L-glycero-2-tetrulose

Diastereoselectivity in the addition of Grignard reagents (RMgX) to 3,4-O-isopropylidene-1-O-triphenylmethyl-L-glycero-2-tetrulose (1) and 1-O-benzoyl-3,4-O-isopropylidene-L-glycero-2-tetrulose (2) depended remarkably on R, X, the solvent, and the reactio
Diastereoselective Synthesis of Enantiomeric Tertiary Alcohols via Nucleophilic Additions to Protected D- and L-Erythrulose Derivatives
Carda, Miguel,Gonzales, Florenzi,Rodriguez, Santiago,Marco, J. Alberto
, p. 1511 - 1514 (2007/10/02)
The diastereoselectivity of the addition of several organometallic reagents to the carbonyl group of protected D- and L-erythrulose derivatives has been investigated.Tertiary alcohols are stereoselectively formed, the diastereomeric ratio being markedly d
Diastereoselective Addition of Organometallics to 3,4-O-Isopropylidene-l-glycero-2-tetrulose Derivatives
Nagano, Hajime,Ohno, Mina,Miyame, Yoko
, p. 463 - 466 (2007/10/02)
Diastereoselectivity in the addition of Grignard reagents (RMgX) to 1-O-benzoyl-3,4-O-isopropylidene-L-glycero-2-tetrulose and 3,4-isopropylidene-1-O-triphenylmethyl-L-glycero-2-tetrulose (2) depended remarkably on X, R, and the reaction temperature.The addition of EtMgBr, i-PrMgBr, and BuMgCl to 2 at 0 deg C gave (2R,3S)-adducts with high diastereoselectivity ( 94percent de).
