标 题 :Process for the synthesis of crystallizable 3,4-polyisoprene and isoprene-butadiene copolymers having high vinyl contents
发明人：HSU WEN-LIANG; HALASA ADEL F
权利人:GOODYEAR TIRE & RUBBER
摘要:Crystallizable 3,4-polyisoprene and isoprene-butadiene copolymers having high vinyl contents can be synthesized in organic solvents to quantitative yields after short polymerization times by utilizing the catalyst systems of this invention. The 3,4-polyisoprene made utilizing this catalyst system is strain crystallizable and can be employed in tire treads which provide improved traction and improved cut growth resistance. This invention specifically discloses a process for the synthesis of 3,4-polyisoprene which comprises polymerizing isoprene monomer in an organic solvent at a temperature which is within the range of about -10 DEG C. to about 100 DEG C. in the presence of a catalyst system which is comprised of (a) an organoiron compound which is soluble in the organic solvent, wherein the iron in the organoiron compound is in the +3 oxidation state, (b) a partially hydrolyzed organoaluminum compound which was prepared by adding a protonic compound selected from the group consisting of water, alcohols and carboxylic acids to the organoaluminum compound, and (c) a chelating aromatic amine; wherein the molar ratio of the chelating amine to the organoiron compound is within the range of about 0.1:1 to about 1:1, wherein the molar ratio of the organoaluminum compound to the organoiron compound is within the range of about 5:1 to about 200:1, and wherein the molar ratio of the protonic compound to the organoaluminum compound is within the range of about 0.001:1 to about 0.2:1.

标题 :Synthesis of 4A-aryl-decahydroisoquinolines
发明人：GLESS RICHARD D; RAPOPORT HENRY; WELLER DWIGHT D
权利人:U S OF AMERICA HEW SECRETARY
摘要:This invention relates to a process for the production of 4a-aryldecahydroisoquinolines where the aryl group is selected as 3-methoxy phenyl. These compounds are morphine analogs and show utility similar to the known morphine, codeine, and thebaine. In this process particular novelty is asserted for the production of a nipecotic ester ethyl 4-(3'-methoxyphenyl)-1-methyl piperidine-3-carboxylate. Furthermore, novelty is asserted for the step of conversion of the nipecotates through cyclization to cis- or trans-tert-butyl 1,6-dioxo-4a-(3'-methoxyphenyl)-2-methyldecahydroisoquinoline-7-carboxylate, which may also be easily converted to the keto amide, trans-1,6-dioxo-4a-(3'-methoxyphenyl)-2-methyldecahydroisoquinoline.
