摘要:THIS PATENT DESCRIBES A PROCESS FOR THE HIGH YIELD SYNTHESES OF THE THREE CLOSO-CARBORANES, 1,5-C2B2H5, 1,6C2B4H6, AND 2,4-C2B5H7 FROM THE NIDO-CARBORANE, 4,5C2B4H8 IN A CONTINUOUS FLOW PROCESS UTILIZING SHORT-TERM HEATING OF 4,5-C2B4H8 AT RELATIVELY HIGH TEMPERATURES. AT ABOUT 460*C. AND 10 MM. ABSOLUTE PRESSURE, THE ABOVEMENTIONED CLOSO-CARBORANES ARE PRODUCED IN THE APPROXIMATE RATIO OF 40:20:40 RESPECTIVELY, WITH ESSENTIALLY NEGLIGIBLE LOSS OF 4,5-C2B4H8, WHILE AT HIGHER TEMPERATURES AND PRESSURES THE PRODUCT RATIO CHANGES SOMEWHATE AND THE YIELDS DECREASE ACCORDINGLY.

摘要:The present invention relates to a process for the preparation of enantiomerically enriched cyclobutylamines of formula (I) from α-tertiary cyclobutanones and reacting said enantiomerically enriched cyclobutylamines to enantiomerically enriched cyclobutylamides. Such compounds are useful intermediates in the synthesis of microbiocidal thiazole compounds.

标 题 :Synthesis of mannojirimycin derivatives
发明人：FLEET GEORGE W J; BRUCE IAN
权利人:MONSANTO CO
摘要:α-Homojirimycin and 6-dpi-homojirimycin are each synthesized from 2-azido-2-deoxy-3,4:6,7-di-O- isopropylidene-D-glydero-D-talo-heptono-1,5-lactone in which the side chain acetonide is hydrolyzed to give the corresponding diol which is then protected with a silyl protecting agent to form a silyl ether. The latter compound is used as a divergent intermediate in which the piperidine ring is formed by joining the nitrogen function at C-2 to C-6 (A) with inversion of configuration at C-6 to form 6-epi-homomannojirimycin or (B) with retention of configuration at C-6 to form α-homomannojirimycin.

标题:Multifunctional synthons as used in the preparation of cascade polymers or unimolecular micelles
发明人：NEWKOME GEORGE R; MOOREFIELD CHARLES N
权利人:UNIV SOUTH FLORIDA
摘要:The bis-homotris compounds 4-amino-4-[1-(3-hydroxypropyl)]-1,7-heptanediol and 4-[1-(3-aminopropyl)]-4-[1-(3-hydroxypropyl)]-1, 7-heptanediol, and organic synthetic methods for their preparation are described. Unique multifunctional aminotriols, as well as their percursors, quaternary nitroalkanes are disclosed as building blocks for unimolecular micelles, as well as new series of cascade polymers. The quaternary nitro compounds which are disclosed allow the synthesis of a new aminotriol containing a quaternary carbon.
