WebWe 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 employing MW heating of substrates with p-TsOH [ 12] . Mechanochemical removal of Boc group by p-TsOH was applied to substrates 1 ... Websous le sceau de l’Université Européenne de Bretagne pour le grade de

WebThe most common strong acid used for dehydration is concentrated sulfuric acid, even though phosphoric acid and p-toluenesulfonic acid (abbreviated as TsOH) are often used as well. The reaction can follow both E1 and E2 mechanisms depending on whether it is a primary, secondary or a tertiary alcohol. Web(p-TsOH) as a catalyst at ambient temperature. Operational simplicity, economic consideration, high yield, short reaction time and low toxicity are the key features associated with this protocol.
