Properties of 3,3-dialkyl-3,4-dihydro-isoquinoline cyclic azomethines
- 40 Downloads
The reactions of 3,3-dialkyl-3,4-dihydroisoquinoline cyclic azomethines with the methyl ester and p-toluidide of iodoacetic acid gave stable quaternary ammonium salts which were suitable dipoles for [3+2] cycloaddition reactions. Azomethines activated by iodomethylation react with potassium cyanide and malonodinitrile.
