Abstract Methyleneaminoacetonitrile(MAAN) resulting from the interaction of formaldehyde, ammonia and hydrogen cyanide on hydrolysis under mildly alkaline conditions gives a number of amino acids and peptides. Various aldehydes react with glycine to give corresponding hydroxyalkyl amino acids, which on reduction with formic acid are converted to reduced amino acids. Formaldehyde reacts with uracil to give 5-hydroxymethyl uracil which on reduction with formic acid yields thymine. Pyrrole formed by heating serine reacts with aldehydes to form porphyrins. Clays do not seem to influence most of these reactions, except the uracil-formaldehyde — formic acid reaction which results in enhanced yield of thymine.
