Synthesis and anti-inflammatory activity of acetylenic thiophenes
摘要:
A series of acetylenic thiophene derivatives have been synthesized via Pd-catalyzed coupling reaction of 2-(butyltelluro)thiophene with a variety of terminal alkynes. These compounds showed good anti-inflammatory activity in the carrageenin-induced paw edema assay on rats. (C) 2001 Elsevier Science Ltd. All rights reserved.
ne, copper iodide could efficiently catalyze the coupling of internal propargylicalcohols with carbondioxide to afford the corresponding α‐alkylidene cyclic carbonates in moderate to excellent yields. Moreover, we have developed a new and versatile protocol for the chemo‐ and stereoselective synthesis of a wide range of (E)‐α‐iodoalkylidene cyclic carbonates from carbondioxide, propargylic alcohols
