A new method for the production of intermediates in the synthesis of an optically active biotin, which comprises reacting a dicarboxylic acid of the formula: ##SPC1## Or its reactive derivative with an optically active primary amine, reducing the resulting trione with a metal hydride, hydrolyzing the resultant amide-alcohol and treating the thus produced lactone with a thiolactonating agent to give a thiolactone of the formula: ##SPC2## , the said trione and amide-alcohol being respectively novel and representable by the formulae: ##SPC3##
