RT Journal Article T1 Fine tuned aminal cleavage: A concise route to differentially protected enantiopure syn-α,β-diaminoesters A1 Viso Beronda, Alma A1 Fernández de la Pradilla, Roberto A1 Flores Aguilar-Amat, Aída A1 López Rodríguez, María Luz A1 García Suárez, Ana Beatriz A1 Alonso Rodríguez, Marta Isabel AB A survey of routes for aminal cleavage of N-sulfinylimidazolidines has been carried out, and selective conditions to cleave the aminal moiety while preserving the sulfinamide group unaltered have been found. Thus, the treatment of enantiopure N-sulfinylimidazolidines with aqueous H3PO4 in THF affords enantiopure N-sulfinyldiamino esters in excellent yields, while the presence of MeOH as cosolvent allows for the simultaneous removal of the sulfinamide group and aminal cleavage. The behavior of these substrates in a variety of chemical transformations has been explored.
