  Synthesis of spiro-substituted 1,3-oxazines by a new sequence leading to spiroheterocycles

  摘要：

  The target compounds, i.e. 1,3-oxazines which are spiro-substituted in position 6 by a piperidine moiety, are derived from 1-oxa-3,9-diaza-spiro [5.5]undecane, a novel heterocyclic parent system. They were all approached by the following three-step sequence: 1,3-dipolar cycloadditions of nitrile oxides and nitrones to piperidines bearing an exocyclic methylene group gave the corresponding spiro-substituted oxazole derivatives 3. In a consecutive step these were cleaved by hydrogenolysis to gamma-amino-alcohols 4, which in a final step were recyclized by insertions of a C-1-unit to yield the target structures 5-10: thus a de facto ring-extension of spiro-oxazoles to spiro-oxazines was accomplished.

  Cycloadditions of nitrile oxides and nitrones to 4,4-methylene-1-methylpiperidine: Studies in regio- and stereoselectivity

  摘要：

  A series of spiro-substituted isoxazole derivatives were synthesized by 1,3-dipolar cycloadditions of nitrile oxides and nitrones to 4,4-methylene-1-methylpiperidine. Since nmr studies confirmed that only one regioisomer was formed selectively, semi-empirical quantum mechanical methods (AM1) were used to rationalize this regiochemical preference via calculation and inspection of HOMO-LUMO-energy and coefficients. X-ray structure analysis carried out for one of these products showed the occurrence of only one stereoisomer, explicable by comparing AM1-calculated DELTAH(f)-values of all possible cycloadducts.

  bicyclic salts so obtained unexpectedly leads to rupture of one of the rings rather than loss of the N-methyl group. The 1-azabicyclo[2.2.1]heptane could be accessed readily via tin hydride-induced cyclization of the corresponding N-phenylethylammonium salt 54, followed by Hofmann elimination with potassium tert-butoxide.
