  In(OTf)3-mediated synthesis of substituted pyridazines

  摘要：

  In(OTf)(3) (4c)-mediated one-pot (4+2) cyclocondensation of gamma-alkynones 3 with N2H4(aq) in dioxane affords substituted pyridazines 5 in good yields via a sequential desulfonative or dehydrogenative aromatization. The facile transformation proceeds by a facile synthetic sequence starting with an alpha-propargylation of beta-ketosulfones 1 and a cyclocondensation of gamma-alkynones 3 with N2H4(aq). The method provides a mild and efficient condition. Moreover, this route can be enlarged to multigram scale. (C) 2015 Elsevier Ltd. All rights reserved.

• From N-sulfonyl,C-homoallyl-hydrazones to pyrazole and pyridazine (N2)-heterocycles: the ultimate aromatization process

  Isomeric six- and five-membered (N-2)-aromatics, 6-methylpyridazines and 5-vinylpyrazoles, which energetic topological aromaticity is comparable to that of benzene, are shown to be efficiently produced by sequential isomerization elimination processes from the corresponding 6-methylidene-1,4,5,6-tetrahydropyridazines and 5-vinylpyrazolines, respectively. The latter precursors are available from the same N-sulfonyl,C-homoallyl-hydrazone substrates by a suitable choice of previously reported conditions for Pd-catalyzed CH-oxidative C,N-ring closing processes. The generality of these cyclization, isomerization, and aromatization reactions, for which detailed mechanisms are proposed, provides a systematic access to wide ranges of 3,4,6-trisubstituted 6-methyl-1,4-dihydropyridazines and 6-methylpyridazines, and their 3,4,5-trisubstituted 5-vinylpyrazole isomers.
