“…[66] A symmetric version of the reaction with aromatic aldimines has also been reported. [67] -Valine methyl ester has been used as a chiral auxiliary with enolate equivalents such as silylenol ethers or silylketene acetals. Rather than using a chiral catalyst, this method uses the chiral amine to generate a chiral imine, thereby producing a diastereomeric pair of products (Scheme 19).…”

Indium and its salts have emerged as promising catalysts for effecting various functional group transformations in last two decades. There are a great number of reported reactions involving indium reagents; the versatility and the applicability of these reactions makes it a hot field to explore, and it attracts much interest from organic chemists. The development of indium reagents in C–C bond‐formation reactions, coupling reactions, asymmetric synthesis in the presence of chiral‐metal ligand complexes, etc. has made this field more attractive. Indium salts have pronounced Lewis acid character and are also attractive because of their moderate stability to water. Here we highlight developments in indium chemistry reported in the last eight years.

“…Our present synthetic approach of these hybrid molecules comprised Mannich type CAC bond forming reactions within dual nature ionic liquids. Mannich-type reactions have been reported in imidazolium [22], pyridium [23], tert. ammonium [24] and phosphonium [25] based ionic liquids.…”

“…Though ionic liquids belong to the class of strongly polar solvents capable to dissolve both organic and inorganic materials, they may be designed non-coordinating, in contrast to polar molecular solvents, to avoid any undesirable binding to metal catalysts in pre-transition states and hence offer great advantages in terms of catalysis and selectivity [1][2][3][4]. In such conditions, metal catalysts exist relatively uncomplexed and their almost bare cations are expected to have higher activity than in traditional polar organic solvents.…”
