A highly efficient protocol for the Pd-catalyzed regioselective Heck arylation of the electron-rich olefin N-acyl-N-vinylamine with aryl halides has been developed. In the presence of hydrogen-bond donor [H 2 NiPr 2 ][BF 4 ] as an additive, this proceeds smoothly in isopropanol to afford exclusively

The indolic ring system is quite activated towards electrophilic substitution but it also undergoes undesirable oxidations and oligomerizations readily. The nitration of indoles, even those substituted with withdrawing groups ~ such as -CN, COOR, NO2, COH2or COR, leads to poor yields of the desired

Heck arylation of N-acyl-3-pyrrolines and an N-acyl-tetrahydropyridine with aryldiazonium tetrafluoroborates under phosphine-free conditions proceeded smoothly to give a-hydroxycarbamates (hemiaminals) or a-alkoxycarbamates which were oxidized to the desired gand d-lactams. Acidic hydrolysis of the
