Evaluation Of Baylis-Hillman Routes To 3-(Aminomethyl)Coumarin Derivatives

The relative merits of two different Baylis-Hillman approaches toward the preparation of coumarin derivatives, containing peptide-like side chains, have been explored. In one approach, use of methyl acrylate as the activated alkene requires a protecting group strategy, an approach that is not necessary when using tert-butyl acrylate.
