In the past, such transformations were carried out under oxidative conditions, and the enantioselective variants were confined to tetrahydroisoquinoline derivatives. Here, we disclose a method for union of N-alkylamines and trimethylsilyl alkynes, without the presence of an external oxidant, and promoted through cooperative actions of two Lewis acids, B(C6F5)3 and a Cu-based complex. A variety of propargylamines
开发了一种将 N-烷基胺的 α-CH 键转化为 α-C-炔基键的有效催化方法。过去,这种转化是在氧化条件下进行的,对映选择性变体仅限于四氢异喹啉衍生物。在这里,我们公开了一种在不存在外部氧化剂的情况下结合 N-烷基胺和三甲基甲硅烷基炔的方法,并通过两种路易斯酸 B(C6F5)3 和 Cu 基络合物的协同作用进行促进。可以高非对映选择性和对映选择性合成多种炔丙胺。生物活性胺的后期位点选择性修饰证明了该方法的实用性。介绍了阐明催化过程的各种机制细微差别的动力学研究。

The identification of Pim-1/2 kinase overexpression in B-cell malignancies suggests' that Pim kinase inhibitors will have utility in the treatment of lymphoma, leukemia, and multiple myeloma. Starting from a moderately potent quinoxalinedihydropyrrolopiperidinone lead, we recognized the potential for macrocyclization and developed a series of 13-membered macro cycles. The structure activity relationships of the macrocyclic linker were systematically explored, leading to the identification of 9c as a potent, subnanomolar inhibitor of Pim-1 and -2. This molecule also potently inhibited Pim kinase activity in KMS-12-BM, a multiple myeloma cell line with relatively high endogenous levels of Pim-1/2, both in vitro (pBAD IC50 = 25 nM) and in vivo (pBAD EC50 = 30 nM, unbound), and a 100 mg/kg daily dose was found to completely arrest the growth of KMS-12-BM xenografts in mice.
