Ja. Stafford et al., A HIGHLY SELECTIVE PROTOCOL FOR THE DEPROTECTION OF BOC-PROTECTED AMIDES AND CARBAMATES, Tetrahedron letters, 34(49), 1993, pp. 7873-7876
A BOC-protected amide or carbamate undergoes mild and selective deprot
ection by treatment with catalytic Mg(ClO4)(2) in acetonitrile. Simple
BOC-protected amines are not affected by these conditions.
