Synthesis of Selective β-Lactam Derivatives

Abstract: In this work, the mild conditions of Mitsunobu reaction were used to convert the hydroxyl group of 6-triphenylmethylaminopenicillanyl alcohol to amines by using different nuleophiles such as phthalimide, di-tert-butyliminodicarboxylate and potassium cyanate. The existence of the β-lactam carbonyl group increased the instability towards nucleophilic attack of refluxing methanol and the four-membered ring was opened. Treating 3-Di-tert-Butoxycarbonylaminomethyl-6-triphenylmethylamino - penicillanate with 50% tri… Show more
