XIII are separated into the individual isomers by PTLC [preparative thin-layer chromatography] on silica gel plates. The structures of the compounds prepared were shown by means of PMR and confirmed by mass spectra obtained in a Finnigan MAT90 instrument with ionizing electrons of 70-eV energy and a
