Item A short and convenient procedure for the stereoselective synthesis of 2-hydroxy-1-norbornanesulfonamides(Tetrahedron: Asymmetry, 2004) Garcı́a Martı́nez, Antonio; Teso Vilar, Enrique; Moreno Jiménez, Florencio; Álvarez Garcı́a, Ana MªA short and convenient procedure for the stereoselective synthesis of novel optically active 2-hydroxy-1-norbornanesulfonamides starting from commercially available natural camphor and fenchone is reported. The synthetic route involves a nucleophilic substitution at the sulfenyl sulfur atom of 2-methylene-1-norbornylthiotriflates followed by oxidation of the intermediate sulfenamides and highly diastereoselective reduction of the carbonyl group of the parent 2-oxo-1-norbornanesulfonamides.Item A novel and simple procedure for the enantiospecific synthesis of bridgehead norbornane thioethers and thiocyanates(Tetrahedron: Asymmetry, 2002) Garcı́a Martı́nez, Antonio; Teso Vilar, Enrique; Moreno Jiménez, Florencio; Álvarez García, Ana María; Pinilla Rodríguez, PatriciaAn easy three-step route for the enantiospecific synthesis of novel 1-norbornyl thioethers and thiocyanates from readily available natural fenchone and camphor is described. The key step of the synthetic route is the nucleophilic substitution over the sulfenyl sulfur atom of the intermediate thiotriflates by the corresponding C-nucleophiles.Item Enantiospecific synthesis of substituted 1-norbornanesulfonic acids and 1-norbornanesulfenic and sulfonic acid derivatives(Tetrahedron: Asymmetry, 2000) Garcı́a Martı́nez, Antonio; Teso Vilar, Enrique; Moreno Jiménez, Florencio; Garcı́a Amo, MaríaNew homochiral 1-norbornanesulfenic and sulfonic acid derivatives 2–7, as well as the sulfonic acids 8, are easily synthesised starting from 2-methylene-1-norbornylthiotriflates 1. This new class of homochiral bridgehead thiosulfonates was prepared by us from naturally occurring (+)-camphor and (−)-fenchone. Nucleophilic substitution at the sulfenyl sulfur atom is the key step for this synthetic strategy
