Abstract
The oxazaborolidine (9)-catalyzed reduction of acetylporphyrins (4) le d to enantiomerically pure hydroxyethylporphyrins (5), which were tran sformed into optically active chlorin derivatives (7 and 8) upon react ion by N,N-dimethylacetamide dimethyl acetal followed by hydrogenation . The absolute configuration of the synthesized chlorins was elucidate d by means of their CD spectra.
