    • Very recently, dichloromethane has been observed to react with carbon nucleophiles, affording methylene-linked symmetric dimers, see: Armstrong, A.; Scutt, J. N. Org. Lett. 2003, 5, 2331-2334.

    • note
    • In the course of the studies to optimize the yield of the glycosylthiomethyl chlorides, it was noted that consistently high yields could be obtained with 0.05 M thiol in dichloromethane. See Experimental Section for details.

    • Unlike entries 1-7, TLC indicated that almost no methylene-linked dimer was produced in entry 8.

    • The NMR spectra of various substituted 1,2,3-triazoles have been studied and the 5-H signals of 1-substituted-1,2,3-triazoles were found to occur at lower field than the 4-H resonance; see: Elguero, J.; González, E.; Jacquier, R. Bull. Soc. Chim. Fr. 1967, 2998-3003.

    • Compounds bearing a methylene group linked to both a heteroatom and a heterocyclic nitrogen atom have been investigated as potential anticancer agents, see: Garcia-Muñoz, G.; Madroñero, R.; Rico, M.; Saldaña, M. C. J. Heterocycl. Chem. 1969, 6, 921-925. On the other hand, the presence of an aromatic heterocyclic group next to the glycosidic bond may enhance the interaction between neoglycoconjugates with lectins by increasing the hydrophobicity, see ref 7 cited in ref 4a.
