A stereoselective total synthesis of SS20846A was efficiently accomplished by means of an intramolecular palladium(ll)-catalyzed cyclization.
Riccardin B, a macrocyclic bis(bibenzy1) possessing cytotoxic activity, and its dehydroxy derivative were synthesized in high yields using the nickel-catalyzed intramolecular coupling of the acyclic precursors.
## Abstract Starting from commercially available pyrroleβ and thiopheneβ2βcarboxylic acids **1** or thiopheneβ and furanβ3βcarboxylic acids **6**, we report the synthesis of tricyclic fused quinolone and naphthyridone derivatives, in only three steps, by an intramolecular Heck cyclization. We also
