OXIDATIVE REACTIONS OF AZINES. 11. THE INFLUENCE OF MANGANESE DIOXIDE ON THE REACTION OF TETRAHYDROPYRIDINES WITH FORMALDEHYDE: SYNTHESIS AND MOLECULAR STRUCTURES OF 3-OXA-7-AZABICYCLO[3.3.1]- AND 6-OXA-2-AZABICYCLO[3.2.1]OCTANES

New derivatives of piperidino[4,5-d]dioxane and 3-oxa-7-bicyclo[3.3.1]nonane were obtained by the oxidatively catalysed condensation of 4-aryl-1,2,3,6-tetrahydropyridines with formaldehyde. The direction of this reaction is sharply altered in the presence of manganese dioxide to give 6-oxa-2-azabicylo[3.2.1]octan-4-one – the product of the oxidative condensation of a new type.
