Isolation and identification of poly-α-(1→4)-linked 3-O-methyl-d-mannopyranose from a hot-water extract of Mycobacterium vaccae
Autor: David Crich, Isabelle V. Farrugia, Michael J. Groves, Afeng Li, Xue-Sheng Mo, Xin‐Xin Tian
Publikováno v: Carbohydrate Research. 324:38-44
A polysaccharide around 3.6 kDa has been identified as the major carbohydrate moiety of a antineoplastic protein–polysaccharide complex (PS4A) obtained by boiling intact cells of Mycobacterium vaccae in water. 1 H and 13 C NMR spectra of this polys

Free Radical Chemistry of β-Lactones. Arrhenius Parameters for the Decarboxylative Cleavage and Ring Expansion of 2-Oxetanon-4-ylcarbinyl Radicals. Facilitation of Chain Propagation by Catalytic Benzeneselenol
Autor: David Crich and, Xue-Sheng Mo
Publikováno v: Journal of the American Chemical Society. 120:8298-8304
2-Oxetanon-4-ylcarbinyl radicals undergo facile ring opening with cleavage of the C−O bond to give 3-butenoxyl radicals which in turn suffer loss of carbon dioxide to provide allyl radicals. When the initial radical is generated from a bromolactone

Nucleotide C4′ radical fragmentation is base-dependent
Autor: Xue-Sheng Mo, David Crich
Publikováno v: Tetrahedron Letters. 38:8169-8172
Nucleotide C4′ radicals undergo radical ionic fragmentation with expulsion of the 3′-phosphate giving a 3′,4′-radical cation. With a series of mononucleotides it is shown that the rate of this fragmentation is a function of the base (T ∼ G
