Abstract:
Title compds. I [Het=aromatic heterocycle R1=H, alkyl, alkanoyl, R2=H, alkenyl, are prepd. Thus, 2-[5-(1-tertiany -butoxyformamide)- 3-(1,2,4-thiacliazolyl) -2-[[(Z)-(tertiarybutoxycarbonyl) methoxyl imino!acetate 2-benzthiazollyl thio ester is treated with 1- chloro-N, N, 2-trimethyl-1-propenamine, triethyl amine, and (3S,4S)- 3-amino-4-carbamoyloxymethyl)-2-oxo-1-azetidine sulfonate. After stirring and evaporating, the resulting residue is reacted with NaHCO3 to give (3S,4S)-3-[(Z)-2-(5-amino-1,2,4thiadiazol-3-yl)-2- [[(t-butoxycarbonyl)methoxy imino!acetamido!4-carbamoyloxymethyl-2- oxo-1-azetidine sulfonate.
