Enantioselective allylation of aldehydes and ketones is a widely used approach for preparing chiral homoallylic alcohols, however, most of the reactions are still mainly performed in organic solvents. Considering their environmental impact, expansion of synthetic technology in water has the highest priority in the organic chemistry field. Here, we report enantioselective reaction of water‐stable amido‐functionalized
the highly enantioselectiveallylation of various isatins with β-amido-functionalized allylstannanes under the influence of indium-based chiralcatalysts and applied this method to the synthesis of 2-oxindole derivatives spiro-fused to an α-methylene-γ-butyrolactone framework. In this communication, we report the successful development of a new catalytic system that enables enantioselective tin-free
Construction of Spiro-Fused 2-Oxindole/α-Methylene- γ-Butyrolactone Systems with Extremely High Enantioselectivity via Indium-Catalyzed Amide Allylation of <i>N</i>-Methyl Isatin
A remarkably effective method allowing an extremely high enantioselectivesynthesis of the spiro-fused 2-oxindole/α-methylene-γ-butyrolactones is described. The key strategy lies in the use of indium-catalyzed asymmetric amideallylation of N-methyl isatin with functionalized allylstannanes, which can lead to the antineoplastic spirocyclic lactones in almost enantiopure forms.
