The present invention provides compounds of formula (I) which inhibit the activity of PI 3-kinase gamma isoform, which are useful for the treatment of diseases mediated by the activation of PI 3-kinase gamma isoform.
Swern oxidation of various benzylic and allylic alcohols, primary alcohols, and secondary alcohols with two ion-supported methyl sulfoxides A-1 (C6) and B-1 (C10), and oxalyl chloride in the presence of triethylamine in dichloromethane, followed by simple diethyl ether extraction of the reaction mixture, gave the corresponding aldehydes and ketones, respectively, in good yields with highpurity. Similarly

The oxidation of primary and secondary alcohols with ion-supported methyl sulfoxide and oxalyl chloride in the presence of triethylamine in dichloromethane efficiently proceeded to give the corresponding aldehydes and ketones, respectively, in good yields with high purity. Isolation of the product was achieved very easily by simple diethyl ether extraction of the reaction mixture and subsequent removal

example of sulfonylation-induced N- to O-acetyl migration of 2-acetamidoethanol derivatives is described. This type of reaction could happen with any 2-acetamidoethanol derivatives under typical sulfonylation conditions (TsCl or MsCl, pyridine) and might be a common side reaction of significance. Furthermore, the results reveal that 2-acetamidoethanol derivatives with a sterically encumbered hydroxyl

As part of a structure-activity exploration into LHRH antagonists, structures containing the thieno[2,3b]pyrrole core were identified as potent antagonists. This letter describes the employment of the Fischer synthesis to access this thienopyrrole and isorneric final compounds. (C) 2009 Elsevier Ltd. All rights reserved.
