    摘要: A method for preparing a new class of protected amino intermediates is provided which utilizes reaction of an imido protected primary amine with a secondary amine. The intermediates thus provided are suitably protected for nucleophilic functionalization on the residue of the primary amine. The desired imido protected amine thus derivatized may be regenerated using acid. Further provided are methods for resolving racemic primary amines. Also provided are β-lactam intermediates protected with the new amino protecting group which are useful in the preparation of β-lactam antibiotics.

    摘要: A method for the production of a maleimide by dehydration and ring-closure of maleinamic acid obtained by the reaction of maleic anhydride with an amine. The method is characterised by effecting ring-­closure imidation of the maleinamic acid by heating the maleinamic acid in a water-insoluble or water-immscible inert organic solvent in the presence of a catalyst. The catalyst is a mixture of the amine salt and the acid, supported on a solid carrier.
