A method for asymmetric alkyl-alkylSuzuki reactions of unactivatedsecondaryalkyl electrophiles, specifically, cross-couplings of racemic acylated halohydrins with alkylborane reagents, has been developed. A range of protected bromohydrins, as well as a protected chlorohydrin and a homologated bromohydrin, are coupled in good ee by a catalyst derived from commercially available components.
已开发出一种用于未活化仲烷基亲电试剂的不对称烷基-烷基 Suzuki 反应的方法,特别是外消旋酰化卤代醇与烷基硼烷试剂的交叉偶联。一系列受保护的溴醇,以及受保护的氯醇和同系溴醇,通过衍生自市售组分的催化剂以良好的 ee 偶联。

The present invention relates to 5-alkylthio-7-[(4-arylbenzyl)amino]-1(2)H-pyrazolo[4,3-d]pyrimidine derivatives of formula I which are effective inhibitors of kinases and exhibit strong antiproliferative and proapoptotic properties on lymphoma cells. This invention further relates to use of said derivatives in the treatment of blood hyperproliferative diseases, such as Non-Hodgkin lymphomas.

Reaction of the title reagent with 1-alkene oxides regioselectively yields the corresponding 1-bromo-2-alkanols, while the more substituted bromide predominates in the cases of styrene oxide and 1-methylcyclohexene oxide.
