Benzonitriles and cyanofluorenes have been rapidly obtained via the [3 + 3] benzannulation of readily available alkynones and α-cyanocrotonates using KOtBu as the only reagent and EtOH (and CO2) is the only by-product.

Herein, we describe the synthesis and reactivity of enamines derived from ylidenemalononitriles and ylidenecyanoacetates. The enamine scope was expanded by (1) increasing yields of aldehyde-derived ylidenemalononitriles, (2) incorporating silyl functionalities, and (3) using other amide acetals to expand the substitution patterns of pyridines resulting from enamine cyclization. In addition, methods
