Selective reduction of alkyne compounds |
| abstract |
A process is provided for the preparation of cyclohexene derivatives of general formula I or II:in which the substituents R1 and R2 independently of one another are defined as follows:R2 is OH or a protective group convertible to a hydroxyl group by hydrolysis,R3 and R4 are hydrogen or C1-C4-alkyl, andR5 is hydrogen or C1-C4-acyl,by the reduction or alkyne compounds of general formula III or IV:wherein the reducing agent used is at least one salt of hyposulfurous acid or hydroxymethanesulfinic acid or a mixture of at least one salt of hyposulfurous acid and at least one salt of hydroxymethanesulfinic acid. |
