Synthesis and Antibacterial Activity of 2‐Alkoxy Penems.
ChemInform(1999)
摘要
The phosphite mediated Oxalimide cyclization reaction was extended to 4-dithiocarbonates of N-oxalyl-2-azetidinones to synthesize 2-alkoxy penems 3. In general, the in vitro antibacterial potency of compounds 3 was weak compared to the highly potent 2-alkylthiopenems 2.
