The oxidation induced rearrangement of carbapenems to carbacephams
摘要:
Upon dihydroxylation, carbapenems with an exocyclic vinyl sulfone at C-2 were found to rearrange to 2-keto-3-hydroxy carbacephams. These products could then be converted into the corresponding carbacephems. (C) 1998 Elsevier Science Ltd. All rights reserved.
An intramolecular addition-elimination strategy for the synthesis of carbapenems
摘要:
The synthesis of 2-[(4-fluorophenylsulfonyl)methyl] carbapenem carboxylate 20 is described. The key step is a base mediated addition-elimination ring closure of a iodovinyl sulfone 12.
