  XH-14 analogues as adenosine antagonists

  摘要：

  Analogues of the potent adenosine antagonist 5-(3'-hydroxypropyl)-7-methoxy-2-(3'-methoxy-4'-hydroxyphenyl)benzo[b]furan-3-carbaldehyde (XH-14, 1) with alternate substituents in the 2-, 5- and 7-positions have been synthesised. The affinity of these compounds for the Al adenosine receptor has been evaluated using a [H-3]CPX competitive binding assay. This structure-activity study highlighted the importance of the 3-formyl and 5-(3-hydroxypropyl) moieties for high receptor affinity. (C) 1998 Elsevier Science Ltd. All rights reserved.

  cross-dehydrogenative coupling of benzylic C(sp3)–H bonds with various alcohols utilizing molecular oxygen as the sole oxidant. This transition-metal-free and chemical-oxidant-free methodology could enable direct and selective alkoxylation of benzylic C(sp3)–H bonds, especially the primary benzylic C–H bond, which is prone to undergo overoxidation. Moreover, the aerobic oxidative C–H/O–H cross-coupling
