Lewis Acid Catalyzed Enlargement of Cyclic β-Alkoxyenals and One-Pot Synthesis of Polyfunctional Enoxysilanes Derived from Aucubin with Trimethylsilyldiazomethane
Pyridines and fused pyridines are accessible by a combination of a Lewis acid-catalyzed multicomponent reaction and aromatization involving loss of a 2-furylmethyl chain.
