标题 :Method for synthesis of colloidal nanoparticles
发明人：STROUSE GEOFFREY FIELDING; GERBEC JEFFREY A; MAGANA DONNY
权利人:UNIV CALIFORNIA
摘要:A method for synthesis of high quality colloidal nanoparticles using comprises a high heating rate process. Irradiation of single mode, high power, microwave is a particularly well suited technique to realize high quality semiconductor nanoparticles. The use of microwave radiation effectively automates the synthesis, and more importantly, permits the use of a continuous flow microwave reactor for commercial preparation of the high quality colloidal nanoparticles.

权利人:ORCHID CHEMICALS & PHARM LTD
摘要:The present invention relates to a new stereoselective method for the preparation of tris-O-substituted-(E)-1-(3,5-dihydroxyphenyl)-2-(4-hydroxyphenyl)ethene derivative of the formula (I) which is a key intermediate in the synthesis of trans-resveratrol (I, R2=R2=R3=H). The invention also provides a method for the exclusive synthesis of trans-isomer of compounds of formula (I) without any contamination of cis-isomer.

摘要:Novel intermediates and method for the chemical synthesis of N-substituted 1,5-dideoxy-1,5-imino-L-fucitol derivatives are provided. A preferred intermediate is 1,5-dideoxy-1,5-imino-3, 4-O-isopropylidene-L-fucitol which is used to prepare the HIV inhibitor 1,5-dideoxy-1,5-imino-[N-ω-methyl caproate]-L-fucitol. These compounds are prepared in a short synthesis from the known compound 2,3-O-isopropylidene-D-lyxono-1,4-lactone or in a multi-step synthesis from D-galactose.
