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. 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
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.
