STUDIES RELATED TO PENICILLINS. PART 26. CONVERSION OF POTASSIUM BENZYLPENICLLINATE INTO 1-SUBSTITUTED DERIVATIVES OF 3-PHENYL-ACETAMIDOAZETIDINE-2,4-DIONE

A new method for the synthesis of azetidine-2,4-diones, involving a Norrish Type II photoreaction of 4-pyruvoylazetidin-2-ones, has been devised.The process features in strategies in which potassium benzylpenicillinate (17a) is converted into 1-substitute

Studies Related to Penicillins. Part 21. β-Elimination Reactions of S,S-Dioxides of Penicillanic Esters

In the presence of 1,5-diazabicyclonon-5-ene (DBN), methyl benzylpenicillinate 1,1-dioxide (3a) is converted into (2S,3R)-1-(1-methoxycarbonyl-2-methylprop-1-enyl)-4-oxo-3-phenylacetamidoazetidine-2-sulphinic acid (5a).Corresponding reactions are o
