(Chemical Equation Presented) Cyclic transformation: The key transformations of the asymmetric total synthesis of the marine-derived natural product seragakinone A are two N-heterocyclic carbene catalyzed benzoin cyclizations that result in the construction of two rings and a pinacol-type rearrangement to install the angular prenyl substituent.
Synthetic Approaches to the Alkaloids of the Ancistrocladaceae: (-)-O-Methylancistrocladine and (+)-O-Methylhamatine

, p. 894 - 896 (2007/10/02)
An asymmetric total synthesis of the naphthylisoquinoline alkaloid (-)-O-methylancistrocladine (2) is described; the synthetic method also provides routes to the atropisomer O-methylhamatine (4) and the enantiomers of these alkaloids.
