Abstract
A highly efficient catalytic enantioselective [4+2] cycloaddition was developed between 2- benzothiazolimines and enecarbamates. A wide range of benzothiazolopyrimidines bearing three contiguous stereogenic centers was obtained in high to excellent yields and with excellent diastereo- and enantioselectivities (d.r. > 98 : 2 and up to >99% ee). Furthermore, this chiral phosphoric acid- catalyzed strategy was scalable and enabled access to a new class of optically pure Lewis base isothiourea derivatives.
