Replacement of the cyclic carbamate in our previously disclosed 1-oxa-3,9-diazaspiro[5.5]undecan-2-one template led to the discovery of two novel series of 3,9-diazaspiro[5.5]undecane and undeca-2-one CCR5 antagonists. The synthesis, SAR, and antiviral activities of these two series are described. One compound (32) was found to have attractive combination of antiviral potency, selectivity, and pharmacokinetic profile. The asymmetric synthesis of 32 was also accomplished and both enantiomers were equally potent. (C) 2008 Elsevier Ltd. All rights reserved.
