A library of 50 copper‐based complexes derived from bisphosphines and diamines was prepared and evaluated in three mechanistically distinct photocatalytic reactions. In all cases, a copper‐based catalyst was identified to afford high yields, where new heteroleptic complexes derived from the bisphosphine BINAP displayed high efficiency across all reaction types. Importantly, the evaluation of the library

An object to be solved by the present invention is to provide a novel pyrrolopyrimidine compound or a salt thereof having an NAE inhibitory action and a cell growth inhibitory effect. The present invention provides a compound or a salt thereof represented by Formula (A), as well as an NAE inhibitor, a pharmaceutical composition, and an antitumor agent comprising the compound or a salt thereof as an active ingredient.
the application! An enantioselective synthesis of axially chiral 1‐arylisoquinolines has been achieved, which involves a rhodium‐catalyzed [2+2+2] cycloaddition of diphenylphosphinoyl‐substituted 1‐arylisoquinolines (see scheme). The new diphenylphosphinoyl‐substituted axially chiral 1‐arylisoquinolines were successfully derivatized to the corresponding axially chiral P,Nligand and Lewis base catalyst

Helquat dyes combine a cationic hemicyanine with a helicene-like motif to form a new blueprint for chiral systems with large and tunable nonlinearoptical (NLO) properties. We report a series of such species with characterization, including determination of static first hyperpolarizabilities β0 via hyper-Rayleigh scattering and Stark spectroscopy. The measured β0 values are similar to or substantially
