A new method for obtaining optically pure 5-norbornene 2-endo-aldehyde derivatives was developed. The reaction of a diastereomeric mixture of the ene acetals 2 and 2′, derived from racemic norbornene aldehydes (±)-1 and chiral nonracemic (S,S)-hyd

The SnCl 4 -promoted rearrangement of 2,2,3,3-tetrasubstituted-2,3-epoxy-1-alcohol derivatives proceeded in a regio- and stereo-controlled manner to selectively give two types of rearranged products from a single isomer by changing the protecting gro

The Lewis acid-promoted rearrangement of 2,2,3,3-tetrasubstituted 2,3-epoxy alcohols with several kinds of protecting groups was investigated. When SnCl4 is used as a Lewis acid, the reaction proceeds in a regio- and stereo-controlled manner to affor

The rearrangements of 2,3-epoxy alcohol derivatives were achieved using the hypervalent iodine(III) reagent, phenyliodine(III) b:is(trifluoroacetate) (PIFA). In the case of 2,3-epoxy alcohols subsequent oxidative ring cleavage occurred to give ω-for
