| titleOfInvention | Stereoselective method of producing 6alpha-fluoropregnanes and intermediaries |
| abstract | 6α-fluorpregnanes (I), where the dotted line betweennpositions 1 and 2 represents a single or double bond; R1 isnOH, OCOR 2 , X, SO 3 R 3 , or an (R 7 )(R 8 )(R 9 )SiO- group, where X isnhalogen, R 2 and R 3 are C 1-6 alkyl or phenyl optionallynsubstituted by C 1-4 alkyl, and R 7 , R 8 and R 9 , equal orndifferent, are C 1-6 alkyl or phenyl optionallynsubstituted by C 1-4 alkyl, can be obtained by means of a highnstereoselectivity process comprising reacting a 3-(trisubstituted)silyloxy-pregna-3,5-dienen(IV) with anfluorinating agent selected among N-fluorosulfonimides and N-fluorosulfonamides.nThe 6α-fluorpregnanes (I) arenintermediates for the synthesis of steroids useful as anti-inflammatorynand anti-asthmatic agents. |
