Is Nosyl 4-nitrobenzenesulfonyl, as the text says? I thought it was 2-nitrobenzenesulfonyl.....
- Fukuyama. "Ns strategies: a highly versatile synthetic method for amines". Chem. Commun. doi:10.1039/b311203a. Seems to say that Ns is the 2-nitro Toby Broom (talk) 00:17, 21 October 2008 (UTC)
In what capacity is a tosyl group protecting an alcohol if it makes it more succeptible to nucleophilic attack? If I'm correct, then this should be changed to say that the tosyl group activates alcohols.

- The real question is protection from what? It activates toward nucleophilic attack at the carbon, but one could say that it protects against deprotonation of the hydroxyl, and perhaps against some oxidation conditions and from having the alcohol act as a nucleophile. --Itub (talk) 15:33, 23 October 2008 (UTC)
