Method for the hydrolysis of azetidinothiazoline compounds

Abstract

A process for preparing compounds having the formula: ##STR1## WHEREIN R is phenoxymethyl or benzyl; R.sub.2 is 1-methoxyethylidene, 1-hydroxyethylidene, or 1,1-dimethoxyethylidene; and R.sub.3 is trichloroethyl, diphenylmethyl, p-nitrobenzyl, trityl, phenyl, naphthyl, or trimethylstannyl; Which comprises treating a compound of the following formula: ##STR2## where R, R.sub.2 and R.sub.3 are as defined above, WITH AgClO.sub.4, AgBF.sub.4, AgIO.sub.4, AgPF.sub.6, CF.sub.3 COOAg, CH.sub.3 SO.sub.3 Ag, CF.sub.3 SO.sub.3 Ag, CH.sub.3 COOAg, or AgNO.sub.3 in aqueous dioxane, aqueous tetrahydrofuran or mixtures thereof.
