    • A new carbonate compound which is N,N'-di-succinimidyl carbonate, N,N'-diphthalimidyl carbonate or N,N'-bis(5-norbornene-2,3-dicarboxyimidyl) carbonate is produced by reacting an N-hydroxy compound of the formulaR-OHwherein R is succinimido, phthalimido or 5-norbornene-2,3-dicarboximido group, with a silylating agent, followed by reacting the resultant silylated product with phosgene, or alternatively by reacting said N-hydroxy compound with trichloromethyl chloroformate either in the molten state or in the presence of a non-polar organic solvent such as xylene. This new carbonate compound is useful not only as a reagent for forming active esters from amino acid but also as a reagent for introducing a carbonyl group between a pair of amino groups, a pair of amino and hydroxyl groups or a pair of amino and mercapto groups, for producing an isothiocyanate from a dithicarbamic acid by removal of hydrogen sulfide from the latter, and for producing acrylic acid derivatives from N-protected serine by dehydration of the latter.
    • 碳酸N,N'-二琥珀酰亚胺酯,碳酸N,N'-二邻苯二甲酰亚胺酯或N,N'-双(5-降冰片烯-2,3-二羧基亚氨基)碳酸酯的碳酸酯化合物是通过使N-羟基 式R-OH的化合物,其中R是琥珀酰亚胺基,苯二甲酰亚氨基或5-降冰片烯-2,3-二羧酰亚胺基,与甲硅烷基化试剂反应,然后使所得的甲硅烷基化产物与光气反应,或者通过使所述N-羟基化合物与 或者在非极性有机溶剂如二甲苯的存在下,氯甲酸三氯甲酯。 这种新的碳酸酯化合物不仅可用作从氨基酸形成活性酯的试剂,而且可用作在一对氨基,一对氨基和羟基之间引入羰基的试剂或一对氨基和巯基 用于通过从后者中除去硫化氢从二硫氨酸生产异硫氰酸酯,并通过后者的脱水由N-保护的丝氨酸制备丙烯酸衍生物。
