Benzylic functionalisation of unactivated toluenes remains a challenge in asymmetric catalysis. Here a chiral Brønsted base catalyses the enantioselective C(sp3)-H functionalization of unactivated alkylarenes, enabling carbon-carbon bond formation a

Catalytic imino-ene-type allylation reactions of unactivated allyl compounds such as propylene were achieved. In the presence of a catalytic amount of a strongly basic K- or NaOtBu-LiTMP mixed system, the desired reactions proceeded smoothly.

Benzylic functionalisation of unactivated alkylarenes remains as a significant challenge in asymmetric catalysis due to their less reactive nature. Here, we show development of catalytic asymmetric C(sp3)–H functionalization of unactivated alkylare

Catalytic benzylic C–H alkylation reactions of alkylarenes with alkenes such as β-substituted styrenes and vinylsilanes have been achieved by utilizing alkylpotassium as a catalyst. Various substituted toluene derivatives can be alkylated under mi

Catalytic addition reactions of very weakly acidic nonactivated alkylarenes such as toluene and its derivatives were developed by using a strongly basic mixed catalyst system under mild reaction conditions. The addition reactions with imines and alke
