Abstract
A new LDA mediated O → C carbamoyl migration, 3 provides a general and efficient route to aryl acetamides 5, precursors to the benzo- and naphthofuranones 7, one of which serves as a starting material for a short synthesis of naturally-occurring benzofuranolactol 11 isolated from several Helenium species.Keywords
