Druais, Valerie,Meyer, Christophe,Cossy, Janine
supporting information; scheme or table, p. 516 - 519 (2012/03/26)
The Noyori transfer hydrogenation of α,β-epoxy and α,β-aziridinyl ynones leads to the corresponding α,β-epoxy or α,β-aziridinyl propargylic alcohols with high reagent-controlled diastereoselectivity.

, p. 707 - 711 (2007/10/03)
An efficient and highly stereoselective construction of the C(9)-C(17) dihydropyran segment of swinholides A-C, which involves a novel reductive cleavage of an epoxy aldehyde by an organoselenium reagent and the intramolecular conjugate addition of an ace
Synthetic Studies on Polypropionate Antibiotics Based on the Stereospecific Methylation of γ,δ-Epoxy Acrylates by Trimethylaluminum. A Highly Stereoselective Construction of the Eight Contiguous Chiral Centers of Ansa-chains of Rifamycins
Miyashita, Masaaki,Yoshihara, Kousei,Kawamine, Katsumi,Hoshino, Masahide,Irie, Hiroshi
, p. 6285 - 6288 (2007/10/02)
A highly stereoselective construction of the eight contiguous chiral centers of ansa-chains of rifamycins has been accomplished by the iterative use of the stereospecific methylation of γ,δ-epoxy acrylates by trimethylaluminum which was recently developed
Pheromone Synthesis, CXXXV. Synthesis of (4R,5R,6S,7E,9E)-4,6,8-Trimethyl-7,9-undecadien-5-ol and Its Antipode, the Female Specific Compound of the Woodroach Cryptocercus punctulatus
Mori, Kenji,Itou, Masamichi
, p. 87 - 94 (2007/10/02)
(4R,5R,6S,7E,9E)-4,6,8-Trimethyl-7,9-undecadien-5-ol (1) and its antipode 1', the female specific compound of the woodroach Cryptocercus punctulatus, were synthesized by starting from methyl (R)-3-hydroxy-2-methylpropanoate (C). Key Words: Chiral centers,
NEW ALLYLSTANNANES FOR THE CONNECTIVE CONSTRUCTION OF MONOPROTECTED VICINAL DIOLS
Keck, Gary E.,Abbott, Duain E.,Wiley, Michael R.
, p. 139 - 142 (2007/10/02)
The preparation of allylstannanes 1a-c, all of which bear an oxygen substituent at the allylic terminus, is desribed.These reagents react with alpha- and beta-alkoxyaldehydes in the presence of MgBr2 as Lewis acid to give SE' products with diastereofacial selectivity consistent with "chelation control"; a syn disposition of substituents about the newly formed bond is highly favored in all cases.
