A new electrochemical iodine(III)‐mediated cyclisation reaction for the synthesis of 4‐(2,2,2‐trifluoroethoxy)isochroman‐1‐ones is presented. Based on this reaction design of experiments and multivariate linear regression analysis were used to demonstrate their first application in an electrochemical reaction. The broad applicability of these reaction conditions could be shown by a range of substrates
We have disclosed a novel metal-free tandem cyclization reaction for the synthesis of 3-methyleneisoindolin-1-ones starting from ester-functionalized aziridines. This strategy can be effectively promoted by DBU and carboxylic acids. Mechanistically, it involves sequential ring opening of aziridines with carboxylic acids, lactamization, and elimination of carboxylic acids.
