3. Has been used as a protecting reagent for the carboxyl group in peptide synthesis: Helv. Chim. Acta, 42, 972 (1959); see 4-Nitrobenzyl chloride, A15749, and Appendix 6. Has also been used in ß-lactam synthesis. Cleavage by sodium sulfide avoids hydrogenolysis problems otherwise encountered with these sulfur-containing nuclei: J. Org. Chem., 43, 1243 (1978).
4. For the protection of alcohols, introduction of the group by the use of silver oxide has been recommended. Selective cleavage can be accomplished with DDQ (2,3-Dichloro-5,6-dicyanobenzoquinone, A11879) or by anodic oxidation. Many other benzyl-type protecting groups are unaffected by these conditions: Tetrahedron Lett., 31, 389 (1990).
