Direct α-arylchalcogenation of acetone with diaryl dichalcogenides has been achieved by using a mixture of TBHP and DTBP oxidants at 120 °C without transition-metal catalyst via oxidative C(sp3)-H bond functionalization. The method exhibits good functional group tolerance and products were isolated in moderate to high yields.

Three positional analogues (4-, 5-, and 7-) of benzothienylglycine and (N-acetylindolinyl)-5-glycine were prepared and coupled to 7-aminodeacetoxycephalosporanic acid (7-ADCA) to give the cephalosporins 17a-c. In addition two isomeric (2,3-b and 3,2-b) th
