2-噻吩基锂置于硼酸三乙酯体系中,用 四氢呋喃 作为反应溶剂,化学反应 1.0H,以10 G的收率获得产物2-噻吩硼酸 参考文献:Synthetic Routes To Fluorescent Dyes Exhibiting Large Stokes Shifts 标题:Synthetic Routes To Fluorescent Dyes Exhibiting Large Stokes Shifts 摘要:Derivatives Of Isomeric 2-(Hydroxytolyl)-4,6-Dimethylamino-1,3,5-Triazines Have Been Synthesized In High Yields In A Controlled Manner Using A Multistep Reaction Sequence. Iodination Of Either 2-(1'-Hydroxy-6'-Methylphen-2'-yl)-Or 2-(1'-Hydroxy-4'-Methylphen-2'-yl)-4,6-Dimethylamino-1,3,5-Triazine With Icl Provides Species Differing In The Positioning Of The Iodo Group Relative To The Hydroxyl Which Readily Undergo Suzuki,Sonogashira,And Heck Reactions Under Pd(0) Catalysis. Thus,Thienyl,Bisthienyl,And 3,4-Ethylenedioxythienyl Groups Have Been Directly Grafted,While Unsubstituted Polycyclic Aromatics Such As Pyrene And Perylene Have Been Linked Via Alkyne Bridges,As Have Ethynyldifluoroborondipyrromethane (Bodipy) Dyes Prepared In Situ. The Presence Of A Hydrogen Bond In The Ground State Involving The Hydroxyl Substituent Has Been Established By Proton NMR And Several X-Ray Structure Determinations. All Of The New Dyes With A Simple Substituent (Phenyl,Thienyl) Exhibited A Pronounced Green Fluorescence Resulting From An Intramolecular Proton Transfer:In:The Excited State (Esipt) Which Produces A Large Stokes Shift (> 10 000 Cm(-1)). With Other Dyes,The Fluorescence Of The Keto Form Responsible For The Esipt Process Could Be Used As The.Input Energy In Efficient Intramolecular Energy Transfer Processes. Replacing Perylene With Pyrene Allowed Reversal Of The Direction Of Energy Transfer From The Polyaromatic Module To The Keto Form. DOI:10.1021/jo301059U

专利号:US-9328109-B2 优先权日:2013-01-14 标 题:Process for the preparation of benzohetero [1, 3] diazole compounds disubstituted with heteroaryl groups 发明人:BIANCHI GABRIELE; PO' RICCARDO 权利人:ENI SPA 摘要:Process for the preparation of a benzohetero-[1,3]diazole compound disubstituted with brominated heteroaryl groups which comprises reacting at least one dihalogenated benzohetero[1,3]diazole compound with at least one brominated heteroaryl compound. Said benzohetero[1,3]diazole compound disubstituted with brominated heteroaryl groups can be advantageously used in the synthesis of compounds useful in the construction of solar concentrators (LSCs—“Luminescent Solar Concentratorsâ€?). Furthermore, said benzohetero[1,3]diazole compound disubstituted with brominated heteroaryl groups can be advantageously used in the synthesis of photoactive polymers useful in the construction of photovoltaic devices (or solar devices) such as, for example, photovoltaic cells (or solar cells), photovoltaic modules (or solar modules), on both rigid or flexible supports. Furthermore, said benzohetero[1,3]diazole compound disubstituted with brominated heteroaryl groups can be advantageously used as precursor of monomeric units in the synthesis of semiconductr polymers.

专利号:US-2023212216-A1 优先权日:2019-12-20 标 题:Synthesis of lactone derivatives and their use in the modification of proteins 发明人:MORRIS ALEXANDER REDFERN; SUTOV GRIGORIJ; BRUNE KARL DIETRICH 权利人:GENIE BIOTECH UK LTD 摘要:Site-specific modifications of proteins are desirable in biotechnological applications such as biopharmaceuticals, immunotherapy, vaccines, and are useful in chemical biology. Gluconoylation is a non-enzymatic, covalent, post-translational modification commonly observed on N-terminal His-Tags bearing proteins. We synthesized glucono-1,5-lactone derivatives, including azido variants for selective acylation. High yield acylation is achieved by simply mixing derivatives with target protein amidst diverse conditions of temperatures, aqueous buffers, excipients, or complex cell lysate.
