Abstract: The present invention provides novel analogs of epicatechin and related polyphenols, their variously functionalized derivatives, process for preparation of the same, composition comprising these compounds and their method of use.

Abstract: In a method for estimating a complexity of a computing job, selected data objects relevant to a data repository are retrieved. In addition, points are assigned to multiple elements of the selected data objects according to a predefined schedule and scores for the selected data objects are calculated by applying a mathematical function to the multiple elements and complexities of the data objects are estimated based upon the calculated scores and the predefined schedule. In addition, a complexity of the computing job is estimated based upon the estimated complexities of the data objects and the estimated complexity of the computing job is stored.

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 by drogenation of the compound obtained from step (ii) to obtain racemic epicatechin.
