SYNTHESIS AND 1,3-DIPOLAR CYCLOADDITIONS OF 2-METHYLENECEPHALOSPORINS

Cephalosporin R- and S-sulphoxides were prepared.The S-sulphoxides gave Mannich-reaction resulting in the formation of 2-methylenecephalosporins.These electrom-deficient dienes underwent 1,3-dipolar cycloadditions with diazoalkanes in a chemo- and regiosp
