Based on this synthetic strategy an efficient method for the synthesis of 2,3-dihydro- 1,2-benzisoxazoles 137 and indazoles was elaborated [77a] (Scheme 57). [Pg.151]

Polymerizable indazole derivatives have received some attention with respect to the preparation of redox polymers and metal ion chelating polymers (73MI11102). Monomers such as 3-vinyl-4,7-dihydro-1//-4,7-indazoledione (63) are readily prepared by 1,3-dipolar cycloaddition of vinyldiazomethane to 1,4-benzoquinones. Crosslinked, low swelling, recyclable redox polymers have been prepared from these monomers. [Pg.279]

The acid-base properties of 4-nitroso-5-aminopyrazoles 50 have been studied. In particular, protonation sites have been determined where salts 51 are formed [66], The effects produced on II, 13C, and 15N chemical shifts by protonation and by hydrogen-bonding solvents on five azoles (imidazole, 4,5-dimethylimidazole, pyra-zole, 3,5-dimethyl-pyrazole, and 4,5-dihydro-3-methyl-2//-benz[g]indazole) have been determined experimentally. Phase effects on the 13C chemical shifts of the C-4 atom of pyrazole were discussed, based both on empirical models and on GIAO calculations of absolute shieldings in different complexes. The special case of the chemical shifts of pyrazoles in the solid state, where they form multiple N-H N hydrogen bonds, was also studied theoretically [88],... [Pg.165]

Pyrazolyl- [85], dihydropyridyl- [86], and pyrrolizinylcarbene complexes [87] have also been subjected to the benzannulation to give the respective oxygenated benzo-N-heterocycles. Finally, a,/ ,y,dienyl carbene complexes containing a heterocyde at the internal double bond have been utilized to prepare 2,3-dihydro-l,2-benzisoxazoles and indazoles by intramolecular benzannulation [60h]. [Pg.284]

D-Glucopyranoside derivatives containing l,3-dihydro-benzoimidazol-2-one, (V), and lH-indazole, (VI), prepared by Urbanski (4) and Patel (5), respectively, were effective in treating insulin resistance syndrome and reducing related risk factors for the development of Type II diabetes. [Pg.332]

Oxo-2,3-dihydro-1//-indazol-2-yl)niethylene](triphenyl)phosphoranes 9 undergo thermal and/or acid-catalyzed rearrangement to yield quinazolin-4(l//)-ones which more likely exist as 4(3/f)-tautomers 10 and triphenylphosphane. Compounds 9 are, in some cases, isolated as intermediates in a thermal rearrangement of [(aryldiazenyl)methylene](triphenyl)phosphoranes (cf. p72). [Pg.98]
