diastereomeric huprines additionally functionalized at position 13 with a methanesulfonamido group have been synthesized in seven steps from the known 9,9-ethylenedioxybicyclo[3.3.1]nonane-3,7-dione (5). In a key-step, nickel boride non-stereoselective reduction of an oxime gave a mixture of amines which was separated as methanesulfonamido derivatives. The substitution pattern of these huprines could lead

A series of structurally novel and metabolically stable bridged bicyclic carbocycle and heterocycle adamantane replacements have been synthesized and biologically evaluated. Several of these compounds exhibit excellent human and mouse 11 beta-HSD1 potency and 11 beta-HSD2 selectivity. (c) 2006 Elsevier Ltd. All rights reserved.
