A compound represented by the general Formula (I) below, or a salt or solvate thereof, which is useful as an ALK inhibitor, and is useful for prophylaxis or treatment of a disease accompanied by abnormality in ALK, for example, cancer, cancer metastasis, depression or cognitive function disorder:
(meanings of the symbols that are included in the formula are as given in the specification).
NHC ligand was found to be highly efficient for the selectivesemihydrogenation of non‐polar unsaturated compounds using a mixture of a silane and an alcohol as reducing agent. The catalytic system was useful for the selectivesemihydrogenation of internal alkynes to (Z)‐alkenes with suppression of overreduction to the corresponding alkanes. Furthermore, semihydrogenations of terminal alkyne, 1,2‐diene
Copper-Catalyzed Highly Regio- and Stereoselective Directed Hydroboration of Unsymmetrical Internal Alkynes: Controlling Regioselectivity by Choice of Catalytic Species
Taking control of boron: A highly regio‐ and stereoselective copper‐catalyzedhydroboration of unsymmetrical internal alkynes has been developed. The regioselectivity was successfully controlled by the choice of catalytic species (copper hydride or boryl copper; see scheme).
