A series of benzothiazinone and benzooxazinone derivatives were discovered as SGLT2 inhibitors. The optimization led to the discovery of compounds 31 and 32, which exhibited similar potency and better SGLT1 selectivity compared to dapagliflozin. These compounds may provide novel promising scaffolds, which are different from phlorizin-based SGLT2 inhibitors. (C) 2011 Elsevier Ltd. All rights reserved.

A rhodium catalyzed SNAr hexafluoroisopropoxylation of unactivated aryl chlorides and bromides was demonstrated. The catalyst activates the aromatic ring via η6-coordination, dramatically facilitating the attack by weakly nucleophilic hexafluoro-2-propanol. Given that fluoroalkyl aryl ethers are valuable structural motifs in bioactive molecules, this method might find utility in medicinal and agricultural
证明了未活化的芳基氯和溴的铑催化 S N Ar 六氟异丙氧基化。该催化剂通过 η 6配位激活芳环,显着促进弱亲核六氟-2-丙醇的攻击。鉴于氟烷基芳基醚是生物活性分子中有价值的结构基序,这种方法可能会在医药和农业化学中发挥作用。
