The preparation of 2,6-substituted piperidine derivatives through diastereoselective C–H functionalization of corresponding nitrogen heterocycles represents an appealing protocol and yet remains a formidable challenge. Here, we describe a stereochemically complementary oxidative C–H functionalization of N-carbamoyl tetrahydropyridines with a wide variety of building blocks, providing either the cis-

A one-pot strategy is devised and applied to the total syntheses of natural products with a THP-ring backbone. A special feature of this one-pot synthesis is the recyclability of the indium complex byproduct generated from the indium-mediated allylation reaction for concurrent catalysis in subsequent steps. Centrolobine and civet cat secretion are synthesized via this new method in overall yields of 58% and 23%, respectively. (C) 2009 Published by Elsevier Ltd.
