| titleOfInvention | Method of stereo-specific reduction of sapogenine-3 |
| abstract | FIELD: medicine; pharmacology. n SUBSTANCE: described method of stereo-specific production of 3(3-hydroxy-5β-H steroid sapogen or its derivatives by reduction of 3-keto,5β-H-steroid sapogenine with steric unfavoured organ-borane. 3β-Hydroxy,5β-H- steroid sapogenine or its derivative can be produced by reduction of 3-keto,5β-H- steroid sapogenine with relatively high steric unfavoured organ-borane reagent used as reducing agent, or by S N 2 transformation of 3α-hydroxy,5β-H- steroid sapogenine or its derivative. Method represents easy way of steroid sapogenine production, such as sarsasapogenine, epysarsasapogenine, smylagenine, epysmylagenine andtheir esters using available or easy-made original substances (e.g., diosgenone, preferably of diosgenine). n EFFECT: improved method of composition production. n 43 cl, 11 ex, 3 tbl, 1 dwg |
