We have used a design of experiments (DOE) approach to optimise rapidly a set of microwave
assisted conditions for the Petasis reaction. The optimal conditions involved the microwave
heating of the reaction components in dichloromethane (1M concentration) at120℃ for
10 min in a focussed microwave (CEM Explorer). These conditions were successfully applied
to a range of Petasis reactions employing either glyoxylic acid or salicylaldehyde as the carbonyl
component along with a number of aryl/heteroaryl boronic acids and amine components.
