, p. 85 - 87 (2003)
(Matrix presented) Catalytic enantioselective epoxidation of homoallylic alcohols using Zr(Ot-Bu)4 and tartrate ester (or tartramide) has been developed. In the Zr(Ot-Bu)4/diisopropyl tartrate-catalyzed epoxidation, the reverse of the enantiofacial preference was observed, depending on the Zr/ligand ratios of 1:1 or 1:2.

The synthesis of (2R)-(+)-1,2-epoxy-4-(triphenylmethoxy)butane from (2R)-(+)-1,2,4-butanetriol through the preferential protection at C4, followed by tosylation at C1 and finally by selective oxyrane-ring formation, is described.
A FACILE CHEMO AND REGIOSELECTIVE REDUCTIVE OPENING OF 1,2 EPOXIDES VIA FREE RADICAL REACTION
Bonini, Carlo,Fabio, Romano Di
, p. 819 - 822 (2007/10/02)
A free radical reaction has been applied to several 1,2 epoxides; the regio and chemoselective reduction of the epoxy ring to afford secondary alcohols occours, in presence of NaI and nBu3SnH in DME at 80 deg C, in rather good yield.
