    • The Alloc group is preferred because Alloc-containing compounds are more convenient to use in solution than the Fmoc derivatives. While the Alloc group has always given good results, on some occasions the presence of the Fmoc has not been compatible with the reaction conditions.

    • An orthogonal system is defined as a set of completely independent classes of protecting groups, such that each class of group can be removed in any order and in the presence of all other classes (G. Barany and F. Albericio, J. Am. Chem. Soc., 107 (1985) 4936, and references cited therein).

    • Removal of the methyl group in the presence of the Fmoc group is not always a straightforward operation.
