Ts. Dalvi et al., ON THE REACTION OF DIPIVALOYLKETENE DIMER WITH OXIMES AND HYDRAZINES - SYNTHESIS OF TETRAOXAADAMANTANES, Heterocycles, 48(9), 1998, pp. 1841-1850
Synthesis of mono-functionalized trioxabicyclo[3.3.1]nona-3,7-dienes (
''bridged bisdioxines'') (3) as well as (7), and their transformation
into the corresponding 2,4,6,8-tetraoxadamantanes (5) and (8), respect
ively, by proton-catalyzed hydrolysis, is described.
