A novel azulene synthesis from the Ramirez ylide involving two different modes of its reaction with activated alkynes

Author affiliations

Abstract

The Ramirez ylide undergoes electrophilic substitution with acetylenedicarboxylates to form Z and E adducts. The latter can react by cycloaddition with another equivalent of the alkyne to provide a new route to novel tetra-substituted azulenes, which show interesting bond localisation and crystal packing effects.
