Palladium‐Catalyzed Reaction of 2,3‐Allenols with Amines: Synthesis of [3]Dendralenes and 1,3‐Dienes Containing Allylic Amino and Hydroxy Groups

Abstract Palladium‐catalyzed reaction of 2,3‐allenols with amines was carried out to construct conjugated polyenes with allylic amino and hydroxy groups. [Pd(π‐allyl)Cl] 2 /P(2‐furyl) 3 ‐catalyzed reaction in MeOH led to ( Z )‐configurated [3]dendralene derivatives and Pd(OAc) 2 /P(2‐furyl) 3 ‐catalyzed reaction in i PrOH resulted in (1 Z ,3 E )‐1,3‐diene derivatives. magnified image
