标题:可回收的树枝状催化剂,用于烯烃的均相二羟基化
摘要:通过离子交换技术,通过混合k 2 Oso 4制备了一系列渗透酸(oso 4 2-)核心树枝状大分子双(季铵溴化)核心树状聚合物,其由聚(苄基醚)树突组成.通过使用渗透性核树枝状聚合物作为均相催化剂,烯烃的二羟基化反应迅速进行,并且通过再沉淀回收树枝状催化剂,然后再使用.此外,观测到树枝状对催化剂的可循环性的影响.在不对称二羟基化反应的情况下,以高化学收率得到适当的对映体过量(ee)的相应的二醇.在这种情况下,不仅树状的catalyst催化剂,而且手性配体也可以通过再沉淀而回收,并且可以有效地重复使用多达五次.

摘要:The present invention relates to a multifunctional reusable catalyst and to a process for the preparation thereof on a single matrix of the support to perform multicomponent reaction in a single pot. The multifunctional catalysts of the invention are useful for the synthesis of chiral vicinal diols by tandem and/or simultaneous reactions involving Heck coupling, N-oxidation and AD reaction of olefins in presence of cinchona alkaloid compounds both as an native one and immobilized one in the said matrix support. This invention also relates to a process for preparing vicinal diols by asymmetric dihydroxylation of olefins in presence of cinchona alkaloid compounds employing reusable multifunctional catalysts as heterogeneous catalysts in place of soluble osmium catalysts.

摘要:The invention includes the synthesis of multivalent metal complexes with boron containing complex organic anions. The complexes include or may include ligands. Complexes capable of being so synthesised are also disclosed as is their use as biocides which fix owing to low aqueous solubility. Intermediates of the process or complexes of the process (after heating or when provided with ligands low on the series) are also useful to strip multivalent metal cations or ligand forming compounds from an aqueous phase (usually by the movement of the complex with the attached multivalent metal cations or ligands into an organic solvent phase), thereby completing the synthesis.

摘要:The present invention relates to racemic propylisopropyl acetic acid and propylisopropyl acetamide and their isomers in their racemic and stereospecific forms, for use in treatment of neurological and psychotic disorders, and affective disorders and to treat pain, headaches and migraines. The isomers are of the compound formula I:wherein R1 is a methyl or ethyl group; R2 is H, methyl or an ethyl group; R3 is ethyl or a propyl group; and R4 is a hydroxyl or amide group; and the total number of carbon atoms in said compound is 8, provided that when R1 is a methyl group and R4 is an amide group, R2 and R3 are not ethyl, further provided that when R1 is an ethyl and R4 a hydroxyl group, only stereoisomers of the compound are referred to. The present invention further relates to a method for the stereoselective synthesis of the 2S and 2R stereoisomer of PID and PIA. The present invention also relates to pharmaceutical compositions containing as an active ingredient a racemic mixture or stereoisomers of the compounds of the general formula (I), which are useful for the treatment of neurological and psychotic disorders, and affective disorders and to treat pain, headaches and migraines.
