For stereochemical investigation of their dehydrogenation, the enantiomers of the aminoalcohols 1, 2, and 3 were prepared from optically active sources, while the enantiomers of the diamines 8 and 9 were available by resolution of the racemates.T he pure antipodes of 1, 2, and 3 reacted with mercury(II)-EDTA by a twofold dehydrogenation via intermediate participation of the neighbouring alcoholic group to the optically active lactams 5, 6, and 7 under complete retention of configuration.In the same manner the diamines 8 and 9 generated by four electron withdrawal the cycloamidines 10 and 11.
