In catalytic chemistry, exploiting catalysts with superior activity and practicability is the
ultimate goal. Herein, we found a brand-new organocatalyst 1-ethyl-3-methylimidazolium …

A new isatin N, N′-cyclic azomethine imine 1, 3-dipole was devised, and an unusual
Michael addition with β-nitrostyrene catalyzed by tributylamine under mild conditions has …

In the past decade, the organocatalytic asymmetric Michael addition has emerged as one of
the most important carbon-carbon bond forming reactions in organic chemistry. As an …

Organo-catalysts for the Michael addition reaction of nitrostyrene with acetone are essential
to improve the efficiency and enantioselectivity, and their recycling also faces great …

The B, N‐bifunctional catalyst homoboroproline has been applied to a catalytic asymmetric
nitroalkene‐Michael addition to β‐nitrostyrene analogues, showing broad substrate …

Nitroalkenes have often been referred to as" synthetic chameleons" owing to their reactivity,
synthetic utility and biological significance. In the last two decades, the reactivity of …

Variation of the activation parameters in the Michael-type reactions (Ad N reactions) offers
an additive mechanistic tool for the studies of these reactions in solution. This approach …

A series of chiral proline amide–thiourea bifunctional catalysts derived from l-proline and
chiral diamine were prepared and successfully applied to highly enantioselective direct …

Herein, we report the synthesis of C2‐symmetric sulfonamides as homogeneous and
heterogeneous organocatalysts and their application in the enantioselective conjugate 1, 4 …
