H‐bond catalysis: The first example of a stereoselectivemulticomponentaza‐Henryreaction catalyzed by a combination of a chiral H‐bond donor organic molecule (thiourea‐ or squaramide‐containing catalyst) and a Lewis base (tertiary amine) in the presence of water is described (see scheme). Each family of catalysts delivers the β‐nitroamine derivative with complementary enantioselectivity, allowing
An environmentally benign method was developed for the three-component, one-pot synthesis of 2-nitroamines by heating a solution of an aldehyde, an aromatic amine, and a nitroalkane in 20% water-methanol at 60 degrees C for five hours in the absence of a catalyst.
