Dl. Wright et al., An imine addition/ring-closing metathesis approach to the spirocyclic coreof halichlorine and pinnaic acid, ORG LETT, 2(13), 2000, pp. 1847-1850
An approach to the spirocyclic core of halichlorine and pinnaic acid has be
en designed around an imine allylation/ring-closing metathesis sequence. Th
is sequence has been used to generate several azabicylo[n.5] model systems.
A newly reported metathesis catalyst was show to be highly effective for c
yclization of these systems.
