However, the pathogenetic role of PVL in staphylococcal infections remains controversial, possibly because it depends on the site of infection. …”

J., Watkin, David J., Petursson, Sigthor“…X-ray crystallography unequivocally showed that protection of the free hydroxyl group of 3,5-O-benzylidene-d-lyxono-1,4-lactone with diphenyldiazomethane proceeded with retention of configuration to give the title compound, C(25)H(22)O(5). …”

730“…The crystal structure of the title compound, C(13)H(14)O(5), establishes (i) the (S) – rather than (R) – configuration at the acetal carbon and (ii) that both the acetal and the lactone form five- rather than six-membered rings; the absolute configuration is determined by the use of 2-C-methyl-d-ribono-1,4-lactone as the starting material. …”
