“…With allyl and chiral ethers, the transformations can proceed with retention of configuration (entries 4, 6, and 7), but racemization has also been observed in some cases (entry 5). Furthermore, the transformation is compatible with functional groups such as cyano groups 172 and chloro or carbonyl substituents (entries 4 and 7, respectively).…”

“…The initial adducts immediately isomerized to conjugated isomers and finally gave ( Z )‐β‐amino acrylamide derivatives upon workup 24. Inter‐ and intramolecular versions of these nitrile addition reactions were applied to the synthesis of biologically active amino furanones and amino sugars such as daunosamine and acosamine 25. Using protected cyanohydrins as the nitrile enolate acceptors, the cross‐Thorpe reaction was achieved once again after many years since the reaction was discovered during the beginning of the 20th century 26.…”
