摘要:The present invention relates to a novel method of synthesis of unsolvated mixed cation borohydrides of a general formula M x M′ y (BH 4 ) z , where M and M′ stand for metal cations, x, y, and z are stoichiometric coefficients. The method of synthesis according to the present invention is characterised in that the precursors having a general formula M[A n ] u and [Cat] v M′(BH 4 ) w are used for the synthesis, where [An] stands for a weakly coordinating anion; [Cat] stands for weakly coordinating cation; u, v, and w are the stoichiometric coefficients; and the synthesis is carried out under an inert to the reagents atmosphere—according to the general reaction equation: x M[An] u +y [Cat] v M′(BH 4 ) w →M x M′ y (BH 4 ) z +xu [Cat][An] where z=yw, xu=yv; M x M′ y (BH 4 ) z is the product of the reaction.

摘要:Methods for the synthesis of CTFE-based block copolymers through iodine transfer polymerization are disclosed. In an exemplary embodiment, a method includes reacting a fluoromonomer “Mâ€? with a chain transfer agent of the formula X—Y or Y—X—Y, wherein X represents a C 1 -C 3 hydrocarbon, a C 1 -C 6 hydrofluorocarbon, C 1 -C 6 hydrochlorofluorocarbon, or C 1 -C 6 fluorocarbon and Y represents iodine or bromine, in the presence of a radical initiator, to form a macro-initiator of the formula: X-poly(M)-Y or Y-poly(M)-X-poly(M)-Y, wherein poly(M) represents a polymer of the fluoromonomer. The method further includes reacting the macro-initiator with chlorotrifluoroethylene (CTFE) in the presence of a radical initiator to form a diblock or a triblock CTFE-based block copolymer of the formula: X-poly(M)-block-poly(CTFE) or PCTFE-block-poly(M)-X-poly(M)-block-PCTFE.

摘要:A single-step, one-pot process to obtain zotarolimus and other rapamycin derivatives on large scale is presented, which improves currently available synthesis schemes. In one embodiment, dried rapamycin is dissolved in isopropylacetate (IPAc). The solution is cooled, and 2,6-Lutidine is added, followed slowly adding triflic anhydride at −30° C. Salts are then removed by filtration. Tetrazole, followed by a tert-base diisopropylethylamine (DIEA) is added to the triflate solution. After incubation at room temperature, the product is concentrated and purified by a silica gel column using THF/heptane as eluant. The fractions containing the product are collected, concentrated, and purified again using an acetone/heptane column. The product containing fractions are concentrated. The product is dissolved in t-BME and precipitated with heptane. The solids are dissolved in acetone, treated with butylated-hydroxy toluene (BHT), and the solution concentrated. The process is repeated twice with acetone to remove solvents. At least one stabilizing agent is added, such as BHT at 0.5% before drying.
