WebTawfik Gharbaoui. 2, Cheng-yi Chen. 3. Abstract: Carbamates, typically used for the protection of amines, including Cbz, Alloc, and methyl carbamate, can be readily deprotected by treatment with 2-mercaptoethanol in the presence of potassium phosphate tribasic in N,N-dimethylacetamide at 75 °C. This nucleophilic deprotection protocol is ... WebSeveral routes to bisulfite adduct 2 were explored, the most efficient of which involved vinyl Grignard addition to 2-indanone followed by ozonolysis and workup with aqueous NaHSO3 to effect reduction and bisulfite formation in a single pot. The safety and calorimetry of this ozonolysis reaction was studied, and the safe scale-up to 3 kg of olefin is described. The …
