A concise synthesis of chiral indanes as α 1A adrenoceptor partial agonists
摘要:
The synthesis of a series of chiral indanes with reported am partial agonist activity is outlined, applying a rhodium catalysed cyclisation for template construction. This method was extended to the asymmetric synthesis of lead compound PF-03774076 (1) which was prepared on >20 g scale in seven steps. Highlights include Rh-mediated cyclocarbonylation and an asymmetric alkene hydrogenation. (C) 2015 Elsevier Ltd. All rights reserved.

A novel series of central nervous system (CNS) penetrant indane 2-imidazoles have been identified as potent, partial agonists of the alpha(1A) adrenergic receptor, having good selectivity over the alpha(1B), alpha(1D) and alpha(2) sub-types. A key structural motif to impart selectivity is a methylene spacer between the indane and a pendant substituent, which includes heterocycles, sulphones and ethers. Introduction of an ortho-halogen to this group led to a lowering of intrinsic efficacy (E-max). (C) 2008 Elsevier Ltd. All rights reserved.
