F Albericio; G Barany. Improved approach for anchoring N alpha-9-fluorenylmethyloxycarbonylamino acids as p-alkoxybenzyl esters in solid-phase peptide synthesis. International Journal of Peptide and Protein Reseach.1985, 26, (1), 92-97.

F Albericio; G Barany. Application of N,N-dimethylformamide dineopentyl acetal for efficient anchoring of N alpha-9-fluorenylmethyloxycarbonylamino acids as p-alkoxybenzyl esters in solid-phase peptide synthesis. International Journal of Peptide and Protein Reseach.1985, 23, (4), 342-349.

This hindered acetal, in conjunction with an alcohol, converts carboxylic acids to esters of that alcohol: Angew. Chem. Int. Ed., 3, 62 (1964); Helv. Chim. Acta, 48, 1746 (1965). For application to the lactonization of -hydroxyacids, giving lactones of up to 16-membered rings, in modest yield, see: Angew. Chem. Int. Ed., 16, 876 (1977). Similarly, can be used to convert primary alcohols to alkylating agents for use in the alkylation of thiols (e.g. 2-Mercaptopyrimidine, A13382): Tetrahedron Lett., 585 (1972).
