There is provided a compound represented by formula (1):
in formula (1), L represents a divalent to tetravalent linking group; D represents a residue obtained by removing 1 to 5 hydrogen atoms from a compound represented by formula (2); m represents an integer of 1 to 10, however, each L may be the same with or different from every other L; n represents an integer of 2 to 10, however, each D may be the same with or different from every other D; and in formula (2), each of R

independently represents a hydrogen atom or a substituent, provided that formula (2) has at least one or more ionic hydrophilic groups.
cycloaddition of β-substituted ene- and thioenecarbamates as well as cyclic enamides with quinone diimides catalyzed by a BINOL- and SPINOL-derived phosphoric acid is reported. A wide variety of 2,3-disubstituted 2-aminoindolines, including polycyclic ones, were prepared in generally high yields (up to 98%) with moderate to complete diastereoselectivities and in most cases excellent enantioselectivities
An efficient zinc-catalyzed amination of free anilines and free phenols with quinoneimides has been disclosed, which proceeds smoothly under simple and mild conditions. The para-selective amination is accomplished on the anilines and phenols via a 1,6-addition pathway, leading to C–N bond formation. The developed protocol offers a promising approach not only for the construction of structurally diverse
