Aminomethylation of lithiated nicotinamide: access to new pyridolactams
摘要:
New 2,3-dihydropyrrolopyridinones were conveniently prepared by trapping lithiated pyridine carboxamides, with highly reactive formimines. In this Letter, we report that a wide range of N-functionalised compounds can be synthesised in one step by this process, allowing the presence of ethers, acetals or ester moieties.

Manufacture of glycinonitriles by reacting amines with carbonyl compounds and hydrogen cyanide under specific reaction conditions in respect of the temperature, reaction time and hydrogen cyanide concentration. The glycinonitriles obtainable by the process of the invention are antioxidants and valuable starting materials for the manufacture of dyes, fungicides, bactericides, textile auxiliaries and inhibitors for use in antifreezes.
