该文章描述了通过取代的甘氨酸前体的多米诺卤化-内酯化反应,有效获取环烯烃环化的苯并恶唑嗪显示轴和中心手性的方法。在N- [2-(1-环己烯-1-基)-6-甲基苯基] -N-甲磺酰基-或-N-芳基磺酰基甘氨酸和溴之间相互作用时,(a R , R )-和 (a S )的轴向手性混合物, S )-杂环的对映异构体与苯并[ e ]环六[ g ] [1,4] oxazocine 核心形成作为主要反应产物,它慢慢地转化为相应的混合物 (a S ,R )- 和 (a R , S )- 对映异构体。这些甘氨酸的N-甲苯磺酰基类似物与碘在相同条件下反应生成螺[4,1-苯并恶氮杂-5,1'-环己烷]结构的杂环。在用分子溴或碘处理这些甘氨酸的环戊烯基同系物N-甲苯磺酸酯后,在这两种情况下,都获得了具有苯并恶唑嗪酮骨架的化合物作为唯一的反应产物。

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,4,8b-hexahydro-cyclopenta[b]indole or itsN-chloroacetyl derivative results in 3-amino-5-methyl-1,2,3,3a,48b-hexahydro- and 5-methyl-1,3a,4,8b-tetrahydrocyclopenta[b]indoles.

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.

The reaction of 2-(2-cyclopentenyl)anilines with I-2 in the presence of NaHCO3 results in formation of 3-iodocyclopenta[b]indoles in high yields. Under similar conditions 2-(2-cyclohexenyl)anilines give rise to cyclization products whose structure depends on the solvent and substituents in the aromatic ring and on the nitrogen atom.
