Palladium catalyzed ring opening of furans as a route to α,β-unsaturated aldehydes
El Kaim, Laurent,Grimaud, Laurence,Wagschal, Simon
, p. 1887 - 1889 (2011)
Furans may be ring opened via pallado-catalyzed reactions leading to α,β-unsaturated aldehydes and ketones tethered to indole and isoquinoline moieties. Besides their synthetic interest, these fragmentations bring interesting elements into the discussion
