    • In theory, the reductive decyanation of α-cyano esters requires only two equivalents of lithium naphthalenide. In practice, however, we found that the use of less than five equivalents of lithium naphthalenide (e.g, 4 equiv) often resulted in incompletion of the reaction under the specified conditions, 45°C, 25 min
