Abstract
A method of producing new, substituted amino-3-tetrazolylpenams of the formula **(See formula)** where Y3 is the acyl radical of an organic, carbamyl or substituted carbamyl acid acylating agent, Y1 is **(See formula)** wherein R1 is R2 or a nitrogen protecting group from tetrazozolylpenam; R2 is hydrogen, trialkylsilyl having 1 to 4 carbon atoms per alkyl group, alkanoyloxymethyl having three to eight carbon atoms, 1-alkanoyloxyethyl having four to nine carbon atoms, phthalidyl or **(See formula)** wherein each of R3, R4, and R5 is hydrogen, chlorine, bromine, fluorine, alkyl having one to four carbon atoms, alkoxy having one to four carbon atoms, or phenyl, characterized by reacting in a solvent inert organic, a compound of the formula **(See formula)** with an isocyanate conversion reagent which is (a) an organic acid acylating agent, (b) ammonia or (c) an amine of the formula X3'NH2, where Y3'is alkyl of 1 to 6 carbon atoms, phenyl, substituted phenyl, naphthyl, or substituted naphthyl, wherein the phenyl or naphthyl substituent is hydroxy, C 1 -C 4 -alkoxy, C 1 -C 4 -alkyl, chlorine, bromine, fluorine, trifluoromethyl, carboxy or carboalkoxy of 2 to 5 carbon atoms.
