In various embodiments, the present invention can involve a method of synthesizing alpha-amino-epsilon-caprolactam. The method can comprise heating a salt of L-lysine in a solvent comprising an alcohol. In other embodiments, the present invention can involve methods for synthesizing epsilon-caprolactam. The methods can comprise heating a salt of L-lysine in a solvent comprising an alcohol and deaminating the reaction product. In various embodiments, the invention can include methods of converting biomass into nylon 6. The methods can comprise heating L-lysine in a solvent comprising an alcohol to produce alpha-amino-epsilon-caprolactam, deaminating to produce epsilon-caprolactam and polymerizing into nylon 6, wherein the L-lysine is derived from the biomass. In other embodiments, the present invention can include methods of making nylon 6. The methods can comprise synthesizing epsilon-caprolactam and then polymerizing, wherein the epsilon-caprolactam is derived from L-lysine.
