Abstract
Isoxazolo[4′,3′:4,5]pyrido- and pyrrolo[2′,3′:4,5]pyrido-[2,3-d]pyrido[1,2-a]-pyrimidines were obtained in the intramolecular cycloaddition reactions of the nitrone and azomethine ylide at the periphery of pyrido[1,2-a]pyrimidin-4(4H)-one system, respectively.

Abstract
[reaction: see text] Intramolecular cycloaddition of novel 1,3-dipoles, N-boranonitrones, was examined. Treatment of O-tert-butyldimethylsilyloximes 9-12 having olefin moieties with 2 equiv of BF3 x OEt2 generated N-boranonitrones, which underwent intramolecular cycloaddition to afford N-nonsubstituted cycloadducts 16 (and/or 18) after extractive workup. Despite the Lewis-acidic conditions, the olefin geometry of the substrates was retained in the cycloadducts in the present cycloaddition. The electronic nature of the N-boranonitrones appeared to be electrophilic. In the case of substrate 11c, having an electron-donating methyl group at an internal position of the olefin moiety, the cycloaddition gave the bridged cycloadduct 18b. The cycloaddition proceeded at relatively low temperature, and the diastereoselectivity was high.

Abstract
Pyrazolo[3,4- d]pyrrolo[2,3- b]pyridine derivatives (6a–f) were obtained by oxidation of tosylhydrazones of 2-allylamino-5-methoxypyrrole-3-carbaldehydes (3a–f) with lead tetraacetate. The nitrilimine intermediates (5a–f) underwent intramolecular 1,3-dipolar cycloaddition to yield the tricyclic heterocycles 6a–f in good yields.
