The total synthesis of tetrahydrohaliclonacyclamine A (5) is described. A key step involves the hydrogenation of an unsaturated bis-piperidine incorporated into a 17-membered macrocycle to provide the cis-syn-cis stereochemistry common to haliclonacyclamines A-D. The hydrogenation product is advanced to the title compound following a five-step reaction sequence. Tetrahydrohaliclonacyclamine A is shown to bind to a variety of ion channels/GPCRs and act as a muscarinic M-1 antagonist. (C) 2010 Elsevier Ltd. All rights reserved.
