摘要: The present invention discloses a process for recovery of a boronic acid of formula R3—B(OH)2, wherein R3 is selected from the group consisting of C1-C6 linear or branched alkyl, C3-C6 cycloalkyl, and C6 aryl, optionally substituted with a group selected from the group consisting of methyl, ethyl, n-propyl, i-propyl, n-butyl, sec-butyl, t-butyl, and phenyl, comprising admixing the boronic acid with a water-immiscible organic solvent in a weight ratio between the boronic acid and the water-immiscible organic solvent from 1:10 to 1:20, adding an aqueous solution to a final pH of neutral, and partitioning the boronic acid into an organic water-immiscible phase and recovery of the organic water-immiscible phase.

摘要: The present invention discloses a process for the preparation of Iopamidol of formula (II) and comprising the following steps: a) reacting the Compound (I) wherein X is OR2 or R3, and wherein R2 and R3 are a C1-C6 linear or branched alkyl, C3-C6 cycloalkyl, C6 aryl, optionally substituted with a group selected from the group consisting of methyl, ethyl, n-propyl, i-propyl, n-butyl, sec-butyl, t-butyl and phenyl, with the acylating agent (S)-2-(acetyloxy)propanoyl chloride in a reaction medium to provide the acetyloxy derivative of Compound (I); b) hydrolyzing the intermediate from step a) with an aqueous solution at a pH comprised from 0 to 7, by adding water or a diluted alkaline solution such as sodium hydroxide or potassium hydroxide, freeing the hydroxyls from the boron-containing protective groups, obtaining the N-(S)-2-(acetyloxy)propanoyl derivative of Compound (II); c) alkaline hydrolysis to restore the (S)-2-(hydroxy)propanoyl group and to obtain Iopamidol (II) and optional recovery of the boron derivative from the solution obtained in step b). The boron-containing protective group is versatile, efficient and recyclable. A one-pot synthesis, without intermediate isolation is provided, leading to a decreasing of recovered and recycled solvents and a significant increasing in the yield, representing a significant advantage in terms of cost-effectiveness of the entire process and environmental awareness.

摘要: Metal-organic framework (MOFs) compositions based on chiral phosphine-, chiral oxazoline-, chiral pyridine-, and chiral diene-derived organic bridging ligands were synthesized and then post-synthetically metalated with metal precursors such as Ru and Rh complexes. The metal complexes could also be directly incorporated into the MOFs. The MOFs provide a versatile family of recyclable and reusable single-site solid catalysts for catalyzing a variety of asymmetric organic transformations, including the addition of arylboronic acids to α,β-unsaturated ketones and alkimines, the hydrogenation of substituted alkene and carbonyl compounds, and cyclization reactions. The solid catalysts can also be integrated into a flow reactor or a supercritical fluid reactor.

摘要: The present invention relates to a composition which comprises at least one α,ω-amino-alkanoic acid or ester and at least one alkanoic ester or acid, characterised in that: the α,ω-amino-alkanoic acid or ester has formula H2N-(CH2)n—COOR, wherein n=9 to 13 and R is an alkyl group or a hydrogen; the alkanoic ester or acid has formula R1-COOR2, wherein R1 is a straight or branched alkyl group with formula CmH2m+1 or CmH2m−3, wherein m=6 to 20 and R2 is an alkyl group or a hydrogen; the molar ratio between the alkanoic acid(s) or ester(s) and the α,ω-amino-alkanoic acid(s) or ester(s) is in the range from 0.001 to 0.4%. The present invention also relates to novel methods for obtaining such a composition.
