Enantiomerically pure tetrahydrofuran compounds and a method for their preparation
(1989) WO1989000160A1- Abstract
- The present invention relates to novel enantiomerically pure intermediary compounds containing specifically substituted tetrahydrofuran structures as well as a method for preparing such intermediary compounds of formula (I), in which the carbon atom in the 2-position has (R)- or (S)-configuration; the substituents in the 2- and 3-positions are trans-related; the substituents in the 3- and 4-positions are cis- or trans-related; X is oxygen, sulphur or -SO2-; R1 is a sterically hindering protecting group; R2 is an organic residue; and the wavy line denotes a connection to the rest of the molecule; the method comprising reacting a compound containing partial formula (II), in which the carbon atom in the 2-position has...

The compounds preferably have formula (Ia), in which R3 is hydrogen or an organic residue and the stereochemistry and the other variables are as defined above. (Less)
