The potential of the oxy-Favorskii rearrangement to form branched cis-fused bicyclic ethers was explored. Both tertiary and quaternary centers were constructed in highly stereospecific manners. Methanol and primary amines were effective nucleophiles for the rearrangement. The total synthesis of (±)-communiol E was achieved based on this method.

3-Hydroxyoctahydro-4H-inden-4-ones and 7-hydroxyoctahydro-1H-inden-1-ones (1, 2 and 3, 4, respectively), as well as the homologous 3-hydroxyoctahydro- 4(1H)-azulenones (5, 6) and 8-hydroxyoctahydro-1(2H)-azulenones (7, 8), were prepared diastereoselective

Phenylseleny bromide-induced cyclisation of γ- and δ-unsaturated aldoxime and ketoxime O-allyl and O-benzyl ethers is followed by a slow fragmentation of the resultant oxyiminium ions furnishing cyclic iminium salts which are readily reduced to pyrrolidines, piperidines or tetrahydroisoquinolines by sodium borohydride; dialkenyl oximes yield indolizidines and quinolizidines by an analogous sequence terminating in a mercury(II)-induced cyclisation.
X=Y-ZH Systems as potential 1,3-dipoles. Part 52: Fused-ring forming electrophile induced oxime→nitrone→cycloaddition cascades

Electrophile induced cyclisation of oximes onto endocyclic alkenes and exo-methylene cycloalkanes occurs stereo- and regio-specifically generating cis-fused bicyclic nitrones in good yield. Subsequent facially selective cycloaddition with N-methylmaleimid
A further breakthrough in biphasic, rhodium-catalyzed hydroformylation: The use of per(2,6-di-O-methyl)-β-cyclodextrin as inverse phase transfer catalyst

Solvent free biphasic hydroformylation of various water-insoluble terminal olefins can be achieved in high yields and selectivities by using a water-soluble rhodium/triphenylphosphine trisulfonate catalyst and per(2,6-di-o-methyl)-β-cyclodextrin as inverse phase transfer catalyst. The catalytic activities were up to ten times higher than those observed without per(2,6-di-o-methyl)-β-cyclodextrin.
