Enzymatic resolution of alcohols via lipases immobilized in microemulsion-based gels
Lipases immobilized in microemulsion-based gel (MBG) were used in the resolution of racemic alcohols, in a new, convenient method of catalysis in organic solvents which employs small amounts of the enzyme.

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.
