21, 22, and 30 involved dehydrophosphonation of the corresponding 2-diphenylphosphono-6-(phenylacetamido)carbapenam precursors 14, 15, and 28 using trimethylsilyl triflate and 1,8-diazabicyclo[5.4.0]undec-7-ene in THF. Syntheses of carbapenems 33-35 involved a Wittig reaction of carbapenam 14 with methyl glyoxylate in the presence of lithium 2,2,6,6-tetramethylpiperidine in THF. For the antibacterial
外消旋的顺式6-(苯基乙酰胺基)卡巴培南(21),2-羟基羰基-顺式6-(苯基乙酰胺基)卡巴培南(22),2-甲氧基羰基-顺式6-(苯基乙酰胺基)卡巴培南(30),2-甲氧基羰基甲基-顺式合成了-6-(苯基乙酰胺基)卡巴培南(33),2-羟乙基-顺-6-(苯基乙酰胺基)卡巴培南(34)和2-乙酰氧基乙基-顺式-6-(苯基乙酰胺基)卡巴培南(35)。在21、22和30中碳青霉烯核的形成涉及使用三氟甲磺酸三甲基甲硅烷基酯和1,8-二氮杂双环[5.4.0]十一月-对相应的2-二苯基膦基-6-(苯基乙酰胺基)卡帕南酰胺前体14、15和28进行脱氢膦化。 THF中的7-烯。碳青霉烯酮33-35的合成涉及碳青霉烯酮14与乙醛酸甲酯在THF中的2,2,6,6-四甲基哌啶锂存在下的Wittig反应。对于针对金黄色葡萄球菌的抗菌活性FDA 209P,S. aureus 95,大肠杆菌ATCC 39188,Klebsiellapneumoniae
