  Ir/f-Ampha配合物催化烯酮的不对称顺序氢化：获得具有两个连续手性中心的手性醇的一般途径

  摘要：

  通过使用铱/f-Ampha 配合物作为催化剂，开发了一种通用且高效的 α,β-不饱和酮的不对称顺序氢化方法，以高收率提供具有两个连续立体中心的相应手性醇，并具有优异的非对映和对映选择性（高达 99% 的产率，>20 : 1 dr 和 >99% ee）。对照实验表明，烯酮的 C C 和 C O 键依次氢化，最终的立体选择性由酮的动态动力学拆分决定。此外，DFT 计算表明，外球途径参与了 C C 和 C的减少。O 烯酮键。该方法的合成效用通过克级反应和极低催化剂负载量 (S/C = 20 000) 和获得抗哮喘药物 CP-199,330 的关键手性中间体的简明合成路线得到证明。

  Synthesis of 2,4-diaryl chromenopyridines and evaluation of their topoisomerase I and II inhibitory activity, cytotoxicity, and structure–activity relationship

  摘要：

  Designed and synthesized were a series of 5H-chromeno[4,3-b]pyridines with substitution at 2- and 4-positions with various 5- or 6-membered heteroaromatics as antitumor agents. They were evaluated for topoisomerase I and II inhibitory activities as well as cytotoxicities against several human cancer cell lines. Structure activity relationship study showed that 2-furyl or 2-thienyl at 2- or 4-position of central pyridine is crucial in displaying topo I or II inhibitory activity and cytotoxicity.

  A series of novel terpyridine-skeleton molecules containing conformational rigidity, 14 containing benzo[4,5]furo[3,2-b]pyridine core and 15 comprising chromeno[4,3-b]pyridine core, were synthesized, and their biological activities were evaluated. 3-(4-Phenylbenzo[4,5]furo[3,2-b]pyridin-2-yl)phenol (8) was determined to be a nonintercalative topo I and II dual catalytic inhibitor and 3-(4-phenylchromeno[4,3-b]pyridine-2-yl)phenol (22) was determined to be a nonintercalative topo II alpha specific catalytic inhibitor by various assays. These two catalytic inhibitors induced apoptosis in addition to G1 arrest in T47D human breast cancer cells with much less DNA toxicity than etoposide. Compounds 8 and 22 significantly inhibited tumor growth in HCT15 subcutaneously implanted xenografted mice. The modification of compounds 8 and 22 with the introduction of a methoxy instead of a hydroxy group enhanced endogenous topo inhibitory activity, metabolic stability in diverse types of liver microsomes and improved pharmacokinetic parameters in rat plasma such as augmentation of bioavailability (41.3% and 33.2% for 2-(3-methoxyphenyl)-4-phenylbenzofuro[3,2-b]pyridine (8-M) and 3-(4-phenylchromeno[4,3-b]pyridine-2-yl)methoxybenzene (22-M), respectively).

  A general and highly efficient method for asymmetric sequential hydrogenation of α,β-unsaturated ketones has been developed by using an iridium/f-Ampha complex as the catalyst, furnishing corresponding chiral alcohols with two contiguous stereocenters in high yields with excellent diastereo- and enantioselectivities (up to 99% yield, >20 : 1 dr and >99% ee).
