Polyprenols, a universal class of glycan-carrier lipids, play important roles in glycan biosynthesis in wide variety of living organisms. The chemical synthesis of natural polyisoprenols such as undecaprenol and dolichols, and even more so the synthesis o

Vancomycin-resistant Staphylococcus aureus (S. aureus) (VRSA) uses depsipeptide-containing modified cell-wall precursors for the biosynthesis of peptidoglycan. Transglycosylase is responsible for the polymerization of the peptidoglycan, and the penicillin-binding protein 2 (PBP2) plays a major role in the polymerization among several transglycosylases of wild-type S. aureus. However, it is unclear whether VRSA processes the depsipeptide-containing peptidoglycan precursor by using PBP2. Here, we describe the total synthesis of depsi-lipid I, a cell-wall precursor of VRSA. By using this chemistry, we prepared a depsi-lipid II analogue as substrate for a cell-free transglycosylation system. The reconstituted system revealed that the PBP2 of S. aureus is able to process a depsi-lipid II intermediate as efficiently as its normal substrate. Moreover, the system was successfully used to demonstrate the difference in the mode of action of the two antibiotics moenomycin and vancomycin. Copyright

As the key compound for the construction of cisoid terpenoids, (2Z,6Z)-8-benzyloxy-1-chloro-2,6-dimethylocta-2,6-diene was sinthesized stereoselectively via the Wittig reaction starting from nerol.The ten-carbon building block was coupled with prenyl or neryl p-tolyl sulfone to afford, after reductive desulfonylation, (Z,Z)-farnesol and (Z,Z,Z)-nerylnerol, respectively.
