Novel approach for synthesis of catechins |
| abstract |
A process for synthesis of enatiomerically pure or enatiomerically enriched or racemic mixture of (+and/or-) epicatechin and its intermediates, comprising the steps of: (i) obtaining penta-protected quercetin; (ii) reducing the penta-protected quercetin obtained from step (i); (iii) optionally deprotecting the compound of step (ii); (iv) reducing the compound obtained from step (ii) or step (iii) in the presence of a chiral/achiral reducing agent to obtain a chiral intermediate; (v) deprotecting and/or hydrogenation of the chiral intermediate obtained from step (iv) to obtain (-)-epicatechin; (vi) optionally simultaneously deprotecting and hydrogenation of the compound obtained from step (ii) to obtain racemic epicatechin. |
