Target preparation strategy selection

Our strategy consisted of the following steps A mixture of potential chiral selectors is immobilized on a solid support and packed to afford a complete-library column , which is tested in the resolution of targeted racemic compounds. If some separation is achieved, the column should be deconvoluted to identify the selector possessing the highest selectivity. The deconvolution consisted in the stepwise preparation of a series of sublibrary columns of lower diversity, each of which constitute a CSP with a reduced number of library members. 

The introduction of conformational restrictions into flexible active molecules is a well-known strategy for trying to increase their potency and/or selectivity toward their biological targets.1 Several methods have been used for constraining flexible molecules. Cyclic derivatives of hnear peptides or peptidomimetics can thus be prepared by reactions involving side-chain...
