3-Oxa-7-azabicyclo 3.3.1 nonanes

There are significantly fewer data available on the conformational behavior of 3-oxa-7-azabicyclo[3.3.1]nonanes than for the 3,7-diaza compounds described above. 

Later, Zhu et al. [70] have also investigated the catalytic activity of thiolate-capped Au25(SR) jg in the stereoselective hydrogenation ofbicyclic ketone 7-(phenylmethyl)-3-oxa-7-azabicyclo[3.3.1]nonan-9-one. In industry, these kinds of cyclic alcohol are synthesized by the reduction ofbicyclic ketones by metal hydrides such as NaBH4. This process will yield equal amounts of two isomers. A 100% stereoselectivity to...
