Synthesis of new spiro-oxindolo-(pyrrolizidines/pyrrolidines) via cycloaddition reactions of azomethine ylides and dibenzylideneacetone
A comparative study of the synthesis of novel spiro-oxindolo(pyrrolizidine/ pyrrolidine) ring systems by the cycloaddition reaction of azomethine ylides generated by a decarboxylative route from sarcosine/proline and isatin with dibenzylideneacetone using various conditions is described. Graphical abstract: [Figure not available: see fulltext.]
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 538-58-9, you can also check out more blogs about538-58-9
