标 题:Stereoselective route to produce tris-O-substituted-(E)-1-(3,5-dihydroxyphenyl)-2-(4-hydroxyphenyl)ethene, an intermediate in the synthesis of trans-resveratrol
发明人：DESHPANDE PANDURANG BALWANT; SENTHILKUMAR UDAYAMPALAYAM PAL; ANDREW GNANAPRAKASAM
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.

发明人：GORALSKI CHRISTIAN T; SINGARAM BAKTHAN; BROWN HERBERT C
权利人:DOW CHEMICAL CO
摘要:A process for the stereospecific synthesis of [E] alkenes from enamines comprising the steps of hydroborating the enamine; esterifying the organoborane so formed and oxidizing the boronic ester in the presence of hydrogen peroxide and in the absence of added base under conditions sufficient to form the [E] alkene in high yield.

标 题:Pyrrole synthesis
发明人：OHRLEIN REINHOLD; BAISCH GABRIELE
摘要:The invention relates to a novel process for the preparation of N-substituted pyrroles, especially of formula (V), wherein the radicals are as defined in the description, by intermolecular aza-Wittig reaction starting from organic azides and 1,4-dioxo compounds. The invention relates also to novel iminophosphorane intermediates for this synthesis. The resulting pyrroles are useful, for example, in the organic synthesis of pharmaceuticals or other active substances and chemicals.
