New general synthesis of tert-butyl 3-amino-2-naphthalenecarboxylates by an electrocyclic reaction of o-quinonedimethides generated from tert-butyl (Z)-3-amino-3-(bicyclo[4.2.0]octa-1,3,5-trien-7-yl)prop-2-enoates
A new general synthesis of tert-butyl 3-amino-2-naphthalenecarboxylates by an electrocyclic reaction of o-quinonedimethides thermally generated from tert-butyl (Z)-3-(bicyclo[4.2.0]-octa-1,3,5-trien-7-yl)prop-2-enoates is described.
