  Selective Synthesis of 7-Substituted Purines via 7,8-Dihydropurines

  摘要：

  A simple and efficient protocol for the preparation of 7-substituted purines is described. 6- and 2,6-Dihalopurines were N-9-tritylated and then transformed to 7,8-dihydropurines by DIBAL-H. Subsequent N-7-alkylation followed by N-9-trityl deprotection with trifluoroacetic acid was accompanied by spontaneous reoxidation, which led to the 7-substituted purines at 55-88% overall isolated yields.

  A rhodium(III)-catalyzed C–H allylation of (hetero)arenes by using 2-methylidenetrimethylene carbonate as an efficient allylic source has been developed for the first time. Five different directing groups including oxime, N-nitroso, purine, pyridine, and pyrimidine were compatible, delivering various branched allylarenes bearing an allylic hydroxyl group in moderate to excellent yields.

  A series of calcineurin inhibiting compounds 1 consisting of a central aromatic N-heterocycle, two aryl substituents and a 3-dimethylaminopropyl chain was synthesized by introduction of the side chain. A corresponding haloheterocycle 3 was transformed into a 3-dimethylaminopropynylheterocycle 2 by Sonogashira coupling and was in turn hydrogenated in the presence of Pd/C to afford the 3-dimethylami

  bond at either the meta or para position by only changing the catalyst system poses a significant challenge. We herein report the [Fe(TPP)Cl]-enabled, selective, C-H difluoromethylation of arenes using BrCF2CO2Et as the difluoromethylation source, which successfully altered the selectivity from the meta to the para position. A preliminary mechanistic study revealed the iron porphyrin complex not only

  仅通过改变催化剂体系在间位或对位直接官能化 CH 键是一项重大挑战。我们在此报告了使用 BrCF2CO2Et 作为二氟甲基化源的 [Fe(TPP)Cl] 启用的、选择性的、CH 二氟甲基化芳烃，这成功地改变了从间位到对位的选择性。初步的机理研究表明，铁卟啉配合物不仅激活了芳环，而且由于配体空间的影响，还诱导了对位选择性。

  We report the direct amidation of arene C-H bonds using sulfonyl azides as the amino source to release N(2) as the single byproduct. The reaction is catalyzed by a cationic rhodium complex under external oxidant-free conditions in the atmospheric environment. A broad range of chelate group-containing arenes are selectively amidated with excellent functional group tolerance, thus opening a new avenue

  unprecedented hybrid‐ruthenium catalysis for distal meta‐C−H activation. The hybrid‐ruthenium catalyst was recyclable, as was proven by various heterogeneity tests, and fully characterized with various microscopic and spectroscopic techniques, highlighting the physical and chemical stability. Thereby, the hybrid‐ruthenium catalysis proved broadly applicable for meta‐C−H alkylations of among others purine‐based

  我们公开了前所未有的用于远端元-C-H激活的混合钌催化。各种非均质性测试证明，杂化钌催化剂是可回收的，并通过各种显微和光谱技术进行了充分表征，突出了物理和化学稳定性。因此，杂化钌催化被证明广泛适用于基于嘌呤的核苷和天然产物缀合物的间位-C-H烷基化。此外，通过可见光照射的元-C-H激活以及对位选择性C-H激活进一步反映了其多功能性。
