Ms. Jensen et al., Synthesis of an anti-methicillin-resistant Staphylococcus aureus (MRSA) carbapenem via stannatrane-mediated Stille coupling, ORG LETT, 2(8), 2000, pp. 1081-1084
A short synthesis of carbapenem 1 is described. The key step involves the c
ross-coupling of an enol triflate with an amino-substituted sp(3) carbon. T
his cross-couping, which allows the introduction of the complete side chain
in one step, utilizes a stannatrane as the heteroalkyl transfer reagent.
