Benzyl protecting group, cleavage

In addition, a catalytic amount of pyridine or ammonium acetate also suppresses the hydrogenolysis of aliphatic 0-benzyl protective group. " Cleavage of phenoUc benzyl ethers, which are more labile than alkyl benzyl ethers, can also be prevented by the addition of 2,2 -dipyridyl (Scheme 83). ° ... [Pg.1024]

A novel procedure for the oxidative removal of benzyl protecting groups by catalytic homogeneous electron transfer has been developed by Schmidt and Steckhan (equation 34)." The selectivity of the reaction can be adjusted by altering the substitution on the aromatic rings of the cation radicals (48). Finally, a recent publication describes a photoinduced single electron transfer initiated oxidative cleavage of benzylic ethers. ... [Pg.248]
