Accurate determinations of the extent to which the SE2' reactions of allyl-, allenyl- and propargylsilanes are stereospecifically anti.

The allylsilanes,R-E- andR-Z-4-trimethylsilylpent-2-ene16, were prepared in essentially an enantiomerically and geometrically pure state er >99.95 : 0.05,E:ZandZ:E>99.95 : 0.05 by, successively, conjugate addition of lithium dimethylcupr...

The synthesis of 3-Oxatetracyclo[5,3,1,12,6,04,9]dodecane (oxaiceane) and 12-Oxatetracyclo[5,3,1,12,5,04,9]dodecane (abeo-oxaiceane) and the reduction of intermediate mercury compounds

Tricyclo[5,3,1,04,9]undec-5-en-2-one (2) was reduced by sodium borohydride to the endo alcohol (3). Oxymercuration-reduction gave a mixture of oxaiceane (4) and abeo-oxaiceane (5) and these were separated and characterized. The intermedi...

Facial Selectivity of the Sharpless Bromine Catalyzed Aziridination

A bromine catalyzed aziridination reaction has been applied to 7,7-dibromo-3-norcarene, which resulted in a highly stereoselective route to cis-4,4-dibromo-8-(toluene-4-sulfonyl)-8-azatricyclo[5.1.0.0]octane in a 46% yield. In order to c...
