  Metal-Free Coupling of Saturated Heterocyclic Sulfonylhydrazones with Boronic Acids

  摘要：

  The coupling of aromatic moieties with saturated heterocyclic partners is currently an area of significant interest for the pharmaceutical industry. Herein, we present a procedure for the metal-free coupling of 4-, 5-, and 6-membered saturated heterocyclic p-methoxyphenyl (PMP) sulfonylhydrazones with aryl and heteroaromatic boronic acids. This procedure enables a simple, two-step synthesis of a range of functionalized sp(2)-sp(3) linked bicyclic building blocks, including oxetanes, piperidines, and azetidines, from their parent ketones.

  three–dimensionality. Herein, we demonstrate a procedurally simple method for the preparation of a range of spirocyclic dihydropyrazoles. The protocol utilises bench stable cyclic tosylhydrazones, which are trivial to prepare from the parent cyclic ketone without need for purification, and commercially available electron deficient alkenes. The synthetic utility of the core scaffold is also demonstrated

  An efficient synthesis of one new (10) and three previously reported (9, 11, and 12) pi-electron donors, which have one sulfur atom in each of the outer five-membered rings attached to the TTF system, is presented. The radical cations derived from 9-11 have been studied by ESR spectroscopy and the spin density distribution of these radical cations, as well as those of other related radical cations, have been determined by MO calculations and correlated with the ESR spectral data. The single-crystal X-ray structures of pi-donors 9 and 12 are reported. The most remarkable fact of these structures is the transverse intermolecular contacts between interstacked molecules. The external sulfur atoms of 9 play a central role in its transverse structural pattern. Complexes of donors 9 and 10 with tetracyano-p-quinodimethane (TCNQ) and tetrafluorotetracyano-p-quinodimethane (TC-NQF(4)) have been obtained and characterized.
