Two individual catalytic platforms (metal‐ and organo‐catalyzed) based on the use of an ionic liquid phase were successfully integrated for the synthesis of α‐cyano‐amine and cyanohydrin trimethylsilyl ethers from allylicalcohol. The right combination of continuous flow processes enabled access to the divergent preparation of two alternative and interesting intermediate compounds from the same starting

The first three-component organocatalyzed Strecker reaction operating on water has been developed. The manifold utilizes ketones (aldehydes) as the starting carbonyl component, aniline as the primary amine, acetyl cyanide as the cyanide source and N,N-dimethylcyclohexylamine as the catalyst.
