1938 Jrnl. Amer. Chem. Soc. 60 398/1 The unimolar tosylation of α- and β-methyl-d-glucosides in pyridine solution with tosyl chloride, followed by acetylation results in the formation of 6-tosyl-triacetyl-α-methyl-d-glucoside.

1975 Nature 30 Oct. 763/1 There is no evidence for a hydrophobic binding pocket or tosyl hole as seen in the α-chymotrypsin structure.

tosylated1972

1972 Jrnl. Chem. Soc.: Chem. Communications 1149/1 We assumed that only nitrogen would be tosylated if both amino- and hydroxy-groups were present in the substrate.

1974 Jrnl. Org. Chem. 39 635/2 A greater chemical shift difference was observed for the C-2 ring protons adjacent to the tosylated nitrogen.

tosylating1938

1938 Jrnl. Amer. Chem. Soc. 60 1203/2 The structure of this compound may be considered proved since it is identical with that obtained..upon tosylating 2,3,4,2′,3′–pentaacetyl-β-methylcellobioside.

1972 Jrnl. Chem. Soc.: Chem. Communications 1148/1 We have found that N-methyl-N-tosylpyrrolidinium perchlorate..can be used as a selective tosylating reagent.
