摘要

IrCl3· 3H2O or FeCl3-catalyzed convenient synthesis of 3-hydroxyphthalates has been achieved by a Diels–Alder reaction of furans with dimethyl acetylenedicarboxylate, followed by ring-opening aromatization reaction of the Diels–Alder adducts, 7-oxabicyclo [2.2. 1] hepta-2, 5-diene derivatives. In addition, 7-azabicyclo [2.2. 1] hepta-2, 5-diene derivative, derived from N-Boc-pyrrole and dimethyl acetylenedicarboxylate, also converted into 3- ...
