专利号:US-12264143-B2 优先权日:2020-12-17 标 题:Synthesis of cannabinoids and cannabinoid precursors, and related compounds, formulations, and methods of use 发明人:SAMMIS GLENN M; ROGGEN MARKUS 权利人:NALU BIO INC 摘要:Methods are provided for the synthesis of cannabinoids, including cannabidiol (CBD), cannabinol (CBN), cannabichromene (CBC), cannabidiolic acid (CBDA), cannabigerol (CBG), cannabigerolic acid (CBGA), cannabidivarin (CBDV), cannabidibutol (CBD-C4), dihydrocannabidiol (DCBD), tetrahydrocannabivarin (THCV), analogs thereof, and precursors to the foregoing. One method employs phloroglucinol or a phloroglucinol analog as a starting material. The syntheses are stereospecific, efficient, selective, and cost-effective, with little or no potential for generation of THC ((−)-trans-Δ9-tetrahydro-cannabinol) or any other psychoactive side product. Telescoped syntheses are also provided, as are new cannabinoids, pharmaceutical formulations, and methods of use.

Further provided is a method for treating cancer in a subject which comprises administering to the subject a therapeutically effective amount of the Eleutherobin derivative.
专利号:US-7211172-B1 优先权日:2002-08-29 标 题 :Method of photochemical synthesis of vitamin Ds 发明人:SALTIEL JACK 权利人:UNIV FLORIDA STATE RES FOUND 摘要:An enhanced photochemical method of making vitamin D includes irradiating a reaction mixture of precursor molecules with light having a wavelength of 254 nm and with light having a wavelength of 313 nm to produce previtamin D, and is followed by heating at a temperature not exceeding 100° C. to convert previtamin D to vitamin D.
专利号:US-5665827-A 优先权日:1996-11-07 标 题:Synthesis of multiblock polymers using group IIA and IIB metal cyclic organometallic initiators 发明人:HALL JAMES E 权利人:BRIDGESTONE CORP 摘要:The invention is a practical process for anionically synthesizing multiblock polymers containing a plurality of blocks formed from polar and/or non-polar monomers by using a cyclic organometallic compound initiator that comprises a divalent metal atom and an organic moiety contained in a ring, preferably a cycloorganomagnesium initiator. Activation of the ring metallic atom results in anionic polymerization of the monomers by addition into the initiator ring at the bonds between the metallic atom and its two adjacent carbon atoms, the metallic atom acting as a bridge between the two living ends of the propagating chain. The active chain ends can be coupled or terminated.
专利号:US-5677399-A 优先权日:1996-11-07 标题:Synthesis of macrocyclic polymers with group IIA and IIB metal cyclic organometallic initiators 发明人:HALL JAMES E 权利人:BRIDGESTONE CORP 摘要:The invention is a practical process for anionically synthesizing commercially significant quantities of macrocyclic polymers from polar and/or non-polar monomers by using Group IIA and IIB metal cyclic organometallic initiators. Activation of the ring metal atom results in anionic polymerization of the monomers by addition into the initiator ring at the bonds between the atom and its two adjacent carbon atoms, the metal atom acting as a bridge between the two living ends of the propagating chain. Coupling of the cyclic polymer living ends by coupling agents produces macrocyclic polymers that are stable in air and moisture and that exhibit desirable properties, such as low viscosities at high molecular weights. Such macrocyclic polymers provide enhanced polymer processability during molding, extruding and the forming of films. Macrocyclic polymers terminated with coupling agents that also provide functional groups may be compounded to produce vulcanizable elastomeric compounds and articles that exhibit reduced hysteresis properties.
