标 题 :Direct synthesis of di-heteroatom containing cyclic organic compounds
发明人：SISKIN MICHAEL; MOZELESKI EDMUND J
摘要:The present invention provides for the simplified, direct synthesis of di-heteroatom containing cyclic organic compounds by forming an aqueous mixture of material of the formula 1 n n nwherein X and Y are heteroatoms which may be the same or different and X is selected from the group consisting of O, S and N, and both Y's are the same and are selected from the group consisting of O, S and N, and R 1 through R 8 are the same or different and are selected from the group consisting of H, C 1 to C 10 alkyl radicals, C 1 to C 10 aryl radicals, C 1 to C 10 alkyl aryl radicals, and z is zero when X and Y are O or S, and z is 1 when X and Y are N, and water at a mole ratio of water to material of formula I in the range of about 10:1 to about 0.001:1 and heating the mixture to a temperature in the range of about 250° C. to about 350° C. under autogeneous pressure for a time of from about 0.5 to 10 hours. Trace amounts of liquid, solid or gaseous acid can be present to further accelerate dehydration, dehydrosulfurization or deamination and cyclization.

发明人：WIMMER ECKARD; MOLLA AKHTERUZZAMAN; PAUL ANIKO V
权利人:UNIV NEW YORK STATE RES FOUND
摘要:A process for the de novo synthesis of a picornavirus using a cell-free medium has been developed. The cell-free medium is prepared from a lysate of mammalian cells from which the nuclei and mitochondria has been removed, endogenous mRNA deactivated and supplemented with nucleoside triphosphates, tRNA, amino acids and precursors necessary for generating proteins. The genomic RNA of the picornavirus or rhinovirus is added to the cell-free medium and after incubation at about 30° C. to 40° C. of from about 4 to 24 hours infectious, mature virus particles are formed.

发明人：TALMA AUKE G; HOOFT HENDRIKA P M; VAN DE BOVENKAMP-BOUWMAN ANNA
权利人:AKZO AMERICA INC
摘要:The present invention relates to an improved synthesis method for the making of citraconimides wherein a citraconic anhydride is reacted with 0.5 to 2.0 equivalents of at least one amine salt. This process may be carried out in a solvent and generally leads to excellent yields of the citraconimides with high selectivity and easy purification. The present inventional so relates to a process for the production of citraconic anhydride from itaconic anhydride with an amine or phosphine catalyst and in a cosolvent.
