The treatment of propargylic azides with silver(i) fluoride in acetonitrile was found to yield α-fluorinated NH-1,2,3-triazoles via the Banert cascade. The reaction was regioselective and the products result from an initial [3,3] rearrangement. The reacti
Selectivity in Garratt-Braverman cyclization of aryl-/heteroaryl- substituted unsymmetrical bis-propargyl systems: Formal synthesis of 7′-desmethylkealiiquinone

Unsymmetrical bis-propargyl ethers and sulfonamides containing various combinations of aryl/heteroaryl substituents at the acetylene termini were synthesized, and their reactivity under basic conditions was studied. Moderate to high (chemo)selectivity was

(Chemical Equation Presented) This letter extends the scope of the rhodium(I)-catalyzed allenic Alder-ene carbocyclization reaction to the preparation of δ- and ε-lactams from amides. A variety of allenic propiolamides were cycloisomerized to give a numbe
