Abstract

Polysubstituted allenes are useful synthetic intermediates in many applications, offering structural complexity, modularity, and their axial chirality in further transformations. While acyl and alkoxy-substituted allenes are known, there are currently few examples of allenes containing both functionalities and no reports of geminally substituted acyl/alkoxy allenes being isolated and characterized. Herein, we report the synthesis of tetrasubstituted allenes featuring a novel geminal acyl/alkoxy substitution. These unique "push-pull" allenes are bench-stable and exhibit interesting reactivity in several applications.
