Preparation of cis-4-O-protected-2-cyclopentenol derivatives |
| abstract |
(57) [Summary]nThe present invention provides a) dissolving 4-O-protected-2-cyclopentenone in a suitable organic solvent, and b) dissolving the solution at a temperature of about -100 ° C to about 20 ° C with a suitable Lewis acid and a suitable reducing agent. And a novel process for producing a cis-4-O-protected-substituted-2-cyclopentenol derivative. The cis-4-O-protected-substituted-2-cyclopentenol derivatives are useful in the preparation of various cyclopentanyl and cyclopentenyl purine analogs useful as immunosuppressants and in the preparation of various prostaglandins.
