Acyl iodides RCOI (R = Me, Ph) reacted with morpholine and piperidine to give the corresponding N-acyl derivatives and morpholine or piperidine hydroiodides. Reactions of acyl iodides with N-methyl- and N-ethylpiperidines involved cleavage of the exocyclic R-N bond with formation of N-acylpiperidine and alkyl iodide and were accompanied (to insignificant extent) by cleavage of the endocyclic N-C bond
chemoselective cascade reaction strategy towards the synthesis of benzo[b]azepines was developed. The method is characterized by simple and mild conditions, low cost, and a wide range of substrates. This method enabled the facile and efficient synthesis of a series of 2,3,4,5-tetrahydro-1H-benzo[b]azepine analogues with an appended fluorinated side chain.
