ether. Tetrazole formation without isolation of the intermediate azide was illustrated by the conversion of the aforementioned nitrile sulfonate into the D-talonotetrazole. Cyclic amidines were prepared from the lactam and lactim ether derivatives. The D-allono derivatives were also converted into D-ribono-1,4 lactam and amidine derivatives.
