A direct retro-Reformatsky fragmentation: formal ring enlargement of cyclic ketones for novel and practical synthesis of heterocyclic enamines.
A novel and practical synthesis of heterocyclic enamines has been developed from the formal ring enlargement of cyclic ketones, which comprised the retro-Reformatsky fragmentation reaction as a key step. Under alkaline bromination conditions, the Reformatsky adducts derived from five- to seven-membe...
