Ring-closing metathesis for the synthesis of 2H- and 4H-chromenes
摘要:
Six 4H-chromenes were synthesized from substituted phenols using vinylstannylation and ring-closing metathesis (RCM) as key steps. In addition, a different approach involving amongst other steps, an aryl allyl isomerization and RCM afforded a set of seven 2H-chromenes from phenolic precursors. (c) 2005 Elsevier Ltd.

Abstract Threenew non-cisplatin analogs [Rh(BID1)(CH3OH)]⋅CH3OH (Rh-1), [Rh(BID2)(CH3OH)]⋅CH3OH (Rh-2) and [Rh(BID3)(CH3OH)]⋅2CH3OH (Rh-3) bearing benzimidazole derivatives (BID1−BID-3) were first prepared as potential anti-tumor compounds. The Rh-3 complex with 8-fluoro group in BID-3 ligand exhibited potential antiproliferative activity against multidrug-resistant human lung adenocarcinoma A549/DDP
