FACILE ACCESS TO CHIRAL OXIRANE BUILDING-BLOCKS FROM (R)-(+)-MALIC ACID: SYNTHESIS OF (2R)-(+)-1,2-EPOXY-4-(TRIPHENYLMETHOXY)BUTANE

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.
