Abstract A convenient synthetic protocol for novel spiro[indoline‐3,2′‐pyrrolo[2,1‐ a ]isoquinoline] and spiro[indoline‐3,2′‐pyrrolo[1,2‐ ]quinoline] motifs was successfully developed by three‐component reaction of isoquinoline (quinoline), cyclohexyl isocyanide, isatylidene malononitriles. In the absence any catalyst, isoquinoline, malononitriles in refluxing dichloromethane gave functionalized ]isoquinolines] good yields with high diastereoselectivity. However, similar quinoline afforded ]quinolines] about 2:1

In this paper, the nucleophilic substitution reactions of various N- and P-containing nucleophiles to MBH carbonates isatins were investigated. Diverse functionalized 3-substituted oxindole derivatives successfully prepared in satisfactory yields with high diastereoselectivity. addition, base-promoted dimerization isatin afforded ethylene-bridged bis(3-methylene)oxindole nearly 4:1 diastereomeric ratios. The relative configurations polycyclic compounds clearly elucidated by determination several single crystal structures.
