N‐alkyl aminomalonates undergo a fast and selective intramolecular C→N acylrearrangement reaction in the presence of a strong base, leading to N‐protected glycinates in excellent yield. Moreover, the fact that the reaction proceeds through a nucleophilic enolate intermediate has been used for implementing a tandem rearrangement/alkylation sequence that has been applied to the preparation of synthetically

(methyl)thio- and -dithiophosphonates and N-alkoxycarbonyl-N-chloromethylglycine or -β-alanine esters and by treatment ofO-alkyl (methyl)dithiophosphonoates andN-acylated amino acids or their esters with paraform in the presence of HCl were developed. The compounds obtained exhibit high insectoacaricide activity and selectivity.
