Chemistry and properties of perhydrobenzo[4.5.6]cholestanes

1997
The investigations undertaken include an intramolecular Michael-aldol approach and a cycloaddition approach to the synthesis ofperhydrobe,nzo[4.5.6]cholestanes. A reaction sequence has been developed to obtain the 3 P-acetoxy-4cx.,5cx. - dihydrobenzo [ 4.5 .6] cholestan-5' (6'H)-one 85 in an optimised yield from the 3Pacetoacetoxy-i:4-6-ketone 71.
