Pomeranz-Fritsch cyclisations are reported using a new reagent boron trifluoride-trifluoroacetic anhydride. Isoquinolines carrying 7-OMe groups have been prepared in good yields and the method extended to the formation of N-substituted indoles and of benzthiophen from the corresponding acetals. Benzofuran could not be obtained by this procedure nor could a Bischler-Napieralski type cyclisation be induced

A protocol for iodine‐catalyzed oxidative rearrangement of tertiary and secondary amines has been developed. This metal‐free protocol provides an atom‐economical, efficient access to synthetically useful α‐amino acid derivatives from readily available acyclic and cyclic tertiary or secondary amines.
