Reaction of Donor‐Acceptor Cyclobutanes with Indoles: A General Protocol for the Formal Total Synthesis of (±)‐Strychnine and the Total Synthesis of (±)‐Akuammicine

Reaction of Donor‐Acceptor Cyclobutanes with Indoles: A General Protocol for the Formal Total Synthesis of (±)‐Strychnine and the Total Synthesis of (±)‐Akuammicine: A ligand‐promoted catalytic [4+2] annulation reaction using indole derivatives and donor‐acceptor (D‐A) cyclobutanes is reported, thus providing an efficient and atom‐economical access to versatile cyclohexa‐fused...
