(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.

Aminoacid hydrochlorides or diaminoacid dihydrochlorides are produced by first reacting a halocarboxylic acid ester with an alkali metal cyanate in the presence of an alcohol to form the corresponding mono- or diurethane and then saponifying this to the corresponding mono- or dihydrochloride. The new process is relatively versatile in its use and above all opens up an elegant synthesis route for lysine.
A diazaphosphacycle may be synthesized by reacting a phosphine with a diimine and optionally one or more equivalents of an acid halide, a sulfonyl halide, a phosphoryl halide, or an acid anhydride in the substantial absence of O2 to form the diazaphosphacycle. The phosphine has the formula R1-PH2 where R1 is a substituted or unsubstituted aryl group, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted cycloalkyl group, or a substituted or unsubstituted ferrocenyl group.
The invention is related to anti-viral compounds, compositions containing such compounds, and therapeutic methods that include the administration of such compounds, as well as to processes and intermediates useful for preparing such compounds.
