| titleOfInvention |
Novel process for preparation of glucocorticoid steroids |
| abstract |
The present invention discloses a process for the preparation of 16, 17-acetals of pregnane derivatives having formula I n n n n n n n n n n wherein each substituent is independently selected from;n R 1 is H or CH 3 ; R 2 is C 1 -C 6 linear or branched alkyl, alkynyl group or cycloalkyl group; aryl or heteroaryl group; or R 1 and R 2 combine to form saturated, unsaturated C 3 -C 6 cyclic or heterocyclic ring; R 3 and R 4 are same or different and each independently represents H or halogen; R 5 is —OH or —OCOR wherein R represents H or C 1 -C 6 linear, branched or cyclic alkyl group that may be substituted. |
