Ad hoc is a main technique for non-infrastructure networks. The performance in ad hoc is affected by the design of routing algorithm. Earlier works consider the scenario that consists at least one end-to-end path between all pair-nodes, call

An efficient total synthesis of enantiomerically pure (−)-dendrobine (1) is accomplished based on an α-carbonyl radical cyclization reaction. (S)-carvotanacetone (6) was converted to bicyclic acetal-enone 4 in five steps. CuI-mediated conjugate ad

Intramolecular cyclization of α-carbonyl radicals to the trimethylsilylacetylenic side chain gives bicyclic vinylsilane ketones and enones. Application of this cyclization to total synthesis of (±)-modhephene is described.
