transfer from manual to automated grinding should facilitate reaction, and mild heat generated in ball milling vessel should be cooperative in deprotection by neat grinding. We have found that the mechanochemical removal of N-Boc group was effected by the solvent-free ball milling of substrate 1 with an excess of p-toluenesulfonic acid (Scheme 1), which is a modification of the procedure

Synthesis and Characterization of 12-Dithiolane Modified

A mild method for the deprotection of thioacetates is described. The reaction can be conveniently carried out at room temperature, and is compatible with a wide range of functionality. The procedure was shown to chemoselectively remove a thioacetate in the presence of an acetate.
