Solvent and in situ catalyst preparation impacts upon Noyori reductions of aryl-chloromethyl ketones: application to syntheses of chiral 2-amino-1-aryl-ethanols
摘要:
As part of medicinal chemistry efforts we found it necessary to develop general syntheses of highly enantiomerically enriched 1-aryl-2-chloroethanols and 1-aryl-2-methylaminoethanols. A survey of literature methods suggested that a truly general approach had not yet been reported, encouraging us to undertake the development of such a methodology. This study describes the design, development, and reduction to practice of a general synthesis of chiral 1-aryl-2-chloroethanols and the transformation of these entities to highly enantiomerically enriched 1-aryl-2-methylaminoethanols. Of particular importance were observations of the impact of solvent and the method of catalyst preparation on the yield and enantiomerical excess of chlorohydrins prepared via Noyori transfer hydrogenations of aryl-chloromethyl ketones.

A novel series of 2-aryl-2-hydroxyethylamine substituted 4-oxo-4,7-dihydrothieno[2,3-b]pyridine-5-carboxamides have been identified as potent antivirals against human herpesviruses. These compounds demonstrate broad-spectrum inhibition of the herpesvirus polymerases HCMV, HSV-1, EBV, and VZV with high specificity compared to human DNA polymerases. (c) 2007 Elsevier Ltd.
