NHC-catalyzed ring expansion of oxacycloalkane-2-carboxaldehydes: a versatile synthesis of lactones.
Li Wang et al.
Organic letters, 11(4), 891-893 (2009-02-10)
Imidazolinium-derived carbenes catalyze the ring-expansion lactonization of oxacycloalkane-2-carboxaldehydes. A variety of functionalized five-, six-, and seven-membered lactones can be formed efficiently under mild reaction conditions. The success of this new method for the construction of lactones is highly influenced by
