Introduction of a Michael acceptor on a flexible scaffold derived from pan-FGFRinhibitors has successfully yielded a novel series of highly potent FGFR4 inhibitors with selectivity over FGFR1. Due to reduced lipophilicity and aromatic ring count, this series demonstrated improved solubility and permeability. However, plasma instability and fast metabolism limited its potential for in vivo studies

Electron rich chromium tricarbonylchloroarene complexes bearing an allyl ether moiety were cyclized under palladium catalysis with concomitant loss of the metal carbonyl fragment to give heterocyclic systems in moderate to good yields. Bimetallic catalysis with palladium and chromium compounds gave rise to cyclization of the parent chloroarenes in moderate yields and with low turnover numbers.
