Tricyclic fused oxazolidinone 3a and 3b have been synthesized as antibacterial agents in 12 and 11 steps respectively. The key intermediates 10a and 10b have been developed via opening of epoxide 9a and 9b and cyclization by the resulting oxygen anion attack.
三环稠合的恶唑烷酮3a和3b已分别以12和11个步骤合成为抗菌剂。关键的中间体10a和10b是通过环氧化物9a和9b的打开并通过所产生的氧阴离子攻击而环化而形成的。
