Abstract: Thiols easily react with [1.1.1]propellane to give sulfur-substituted bicyclo[1.1.1]pentanes in radical reactions, but this reactivity is not replicated in the case of heterocyclic thiols. Herein, we address this issue by electrophilically activating [1.1.1]propellane to promote… read more here.

Abstract: A highly chemo-, regio-, and stereoselective glycolate aldol reaction of sulfur-substituted enediolates with aldehydes was developed by employing a l-cyclohexylglycine-derived chiral iminophosphorane as a catalyst. The key for establishing this protocol is the distinct ability… read more here.

Abstract: Sulfur‐substituted nucleobases (a.k.a., thiobases) are among the world's leading prescriptions for chemotherapy and immunosuppression. Long‐term treatment with azathioprine, 6‐mercaptopurine and 6‐thioguanine has been correlated with the photoinduced formation of carcinomas. Establishing an in‐depth understanding of… read more here.
