Synthesis of 2-amino-2,3-dihydrobenzofurans and fully substituted furans from modified Baylis–Hillman adducts

Abstract

Syntheses of 2-amino-2,3-dihydrobenzofuran derivatives 3a– g and fully substituted furans 5a– f were achieved starting from the Baylis–Hillman adducts. We prepared 2-amino-2,3-dihydrobenzofurans from the Baylis–Hillman adducts of methyl and ethyl acrylates and fully substituted furans from the Baylis–Hillman adducts of alkyl vinyl ketones.
