权利人:SUMITOMO CHEMICAL CO
摘要: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## n 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## n , the said trione and amide-alcohol being respectively novel and representable by the formulae: ##SPC3##

权利人:UNIV KING FAHD PET & MINERALS
摘要:A method for enhancing the conductivity of MOF-5 by the development of an MOF-5 polymer composite material. The composite material incorporates a conductive polymer, preferably polyaniline, in the solvo-thermal synthesis pathway of MOF-5. The electrically conductive MOF-5 composite exhibits electric conductivity three orders of magnitude higher than that of MOF-5 while maintaining the crystallinity, robustness, and thermal stability of MOF-5.

标 题:Optically active imidazolidin-2-one derivatives
发明人：HAZAMA MOTOO; ARATANI TADATOSHI; SUZUKAMO GOHU; TAKAHASHI TAKEO
权利人:SUMITOMO CHEMICAL CO
摘要:A novel optically active cis-4,5-disubstituted imidazolidin-2-one derivative of the formula: wherein R1 is a C1-C4 alkyl group or benzyl and R2 is a chiral aralkyl group optionally having at least one of C1-C4 alkyl, C1-C4 alkoxy and hydroxyl groups is produced asymmetrically by the reaction of 1,3-dibenzyl-cis-4,5-dicarboxy-imidazolidin-2-one or its anhydride with an optically active secondary amine of the formula: wherein R1 and R2 are each as defined above and is transformed into the lactone of 1,3-dibenzyl-cis-4-carboxy-5-hydroxymethyl-imidazolidin-2-one, which is a key intermediate in the synthesis of d-biotin.
