Intramolecular [3+2]-cycloaddition was studied of munchnones generated at heating syn- and anti-atropisomers of N-acyl-N-[6-methyl-2-(cyclopent-2-en-1-yl)phenyl]glycines with acetic anhydride. By spectral and X-ray diffraction analysis syn-isomers of acids and tetrahydro-1,4,7-methanetriyl[1,3]oxazolo[3,4-a][1]- bensazocin-3(3aH)-ones were identified.

When reacting with I2, 2-(cyclopent-2-enyl)anilines undergo cyclization into 3-iodo-1,2,3,3a,4,8b-hexahydrocyclopenta[b]indoles in high yields. The minor reaction products were 3,5-or 3,7-diiodoindolines. Ammonolysis of 3-iodo-5-methyl-1,2,3,3a

The reaction of N-acetyl-2-(cyclohex-1-enyl)aniline with Br2 or N-bromsuccinimide at 20 °C is accompanied by intramolecular cyclization to give brominated 3,1-benzoxazines or 4-acetyl-3-bromo-5-methyl-1,2,3,3a,4,8b-hexahydrocyclopenta[b]indole.
