Highly Enantiospecific Oxyfunctionalization of Nonactivated Hydrocarbon Sites by Perfluoro-cis-2-n-butyl-3-n-propyloxaziridine
摘要:
[GRAPHICS]Nonactivated hydrocarbon sites of enantiopure compounds are oxyfunctionalized enantiospecifically by perfluoro-cis-2-n-butyl-3-n-propyloxaziridine under remarkably mild reaction conditions. The reaction occurs with retention of configuration at the oxidized stereogenic center, and the enantiospecificity is highly independent from both the carbon framework of the substrate and the presence of functional groups.
Electrooxidative cleavage of carbon-carbon bonds. 2. Double cleavage of .alpha.,.beta.-epoxy alkanones and enantiospecific syntheses of chiral methyl trans- and cis-chrysanthemates from (+)- and (-)-carvones

Benzopyrans are selective estrogen receptor (ER) beta agonists (SERBAs), which bind the ER subtypes alpha and beta in opposite orientations. Here we describe the syntheses of cyclopentanone and cyclohexanone intermediates for SAR studies of the Gring on the benzopyran scaffold. Modification of the C-ring disrupts binding to ER alpha, thus improving ERP selectivity up to 100-fold. X-ray cocrystal structures confirm previously observed binding modes. (c) 2007 Elsevier Ltd.
