Bicyclohexan-2-one (1) was converted into the 3-diazo derivative (4) wich was ringcontracted thermally to give a variety of amides and esters of bicyclopentane-2-carboxylic acid as exo- and endo-stereoisomers.Conversion of the acids into the corresponding methyl ketones and then Baeyer-Villiger reaction has led to endo- and exo-bicyclopentan-2-yl acetates wich differed markedly in solvolytic reactivity.
PARTIAL ASYMMETRIC SYNTHESIS OF ATROPISOMERIC 1,1'-BINAPHTHYLS VIA THE ULLMANN COUPLING REACTION OF CHIRAL ALCOHOL ESTERS OF 1-BROMO-2-NAPHTHOIC ACID

The Ullmann coupling of 1-bromo-2-naphthoates of C-chiral alcohols of R- and S-configuration induced axial dissymmetry of R- and S-chirality, respctively, in the newly formed 1,1'-bond of the binaphthyls; the optical yield amounted up to 13percent where the chiral alcohol was l-menthol.
