A tetracyclic dinitrile was synthesized in twelve steps from cyclohex‐2‐en‐1‐one by using a chelation‐triggered conjugate addition to a γ‐hydroxy‐substituted α,β‐unsaturated nitrile and an oxidative dearomatization/Diels–Alder cycloaddition cascade as the key steps. The first total synthesis of azitine (in 17 steps) was achieved through a simple reductive cyclization of this intermediate and subsequent

The 15-acetoxyazomethine derivative of atisine was prepared from atisine base. Its structure was confirmed by converting it to atisine 15-hydroxyazomethine and proved by an XSA. Atisine 15-acetoxyazomethine exhibited antiarrhythmic activity in rat cardiac arrhythmia models induced by CaCl2 and aconitine. Atisine 15-acetoxyazomethine, in contrast with atisine 15-hydroxyazomethine, exhibited local anesthetic activity.
