标 题 :Chemicals and use of hypohalites in mechanism-based selective dual radical organic synthesis
发明人：PALOMINO EDUARDO
权利人:WALKER CANCER RES INSTITUTE INC
摘要:The synthesis of pattern-specific compounds using hypohalites, such as hypochlorous acid, sodium hypochlorite, and potassium hypoiodite, as dual-radical generators is provided. The synthesis can be implemented by a cyclization reaction, a dehydrogenation reaction, a hydroxylation reaction, a decarboxylation reaction, or any combination of the above four. The reactions are typically carried out in water, in a nonpolar solvent such as ethyl acetate, or a mixture of both. Hypochlorous acid is made by adding a weak acid such as acetic acid to sodium hypochlorite.

摘要:The present invention relates to a process for the deprotection of protected amine compounds, wherein the protected amine compound is contacted with an electrophilic oxidating agent that is optionally formed in situ, said electrophilic oxidating agent being selected from the group of I 2 , Br 2 , Cl 2 and compounds comprising a halogen atom having a formal oxidation state of 1+, 3+, 5+ or 7+, provided that the electrophilic oxidating agent is not iodobenzene diacetate. The process can be conveniently employed in the synthesis of 1,3-amino alcohols, β-amino acids and heterocyclic compounds, in particular β-amino acids.

摘要:(7-APCA) having the formula (I) ##STR1## which is an important synthesis intermediate in the preparation of cephalosporin-like antibiotics, is prepared by treating a compound of the formula (II) ##STR2## in which R 1 and R 2 represent alkyl, aryl and aralkyl radicals, with a strong protonic acid or with a Lewis acid. Compound (II) is prepared by adding triphenylphosphine and alkali metal iodide to a compound of the formula (VI) ##STR3## then reacting with acetaldehyde in base. Compound (VI) is prepared by treating a compound of the formula (VII) ##STR4## with a base in a polar solvent at -70° C. to 0° C. Compound (VII) is prepared by treating a compound of the formula (VIII) ##STR5## with a chlorinating agent in an organic solvent.
