Highly enantioselective Mannich reactions of imines bearing a benzothiazole moiety with tert-Butyl acetoacetate (cas 1694-31-1), catalyzed by a cinchona-based squaramide organocatalyst have been developed. The corresponding benzothiazole β-keto ester derivatives were obtained in high yields (up to 99%) and with excellent enantioselectivities (up to 98% ee).
