    摘要: A process for preparing optically active (S)-(-) and (R)-(+)-deoxyspergualin and salts thereof of the formula I ##STR1## by reacting a compound of formula II ##STR2## with a compound of formula III ##STR3## in the presence of a condensing/dehydrating agent and an organic or inorganic base in an organic solvent to form a compound of formula IV ##STR4## which can then be converted to the desired final product of formula I via deprotection and hydrogenolysis. The invention also comprises the compounds of the formula II, IV and VII ##STR5##
