Chiral 1,1′-binaphthylazepine derived amino alcohol catalyzed asymmetric Henry reaction
The catalytic asymmetric Henry reaction of nitromethane to various aldehydes has been developed using a chiral binaphthylazepine derived amino alcohol and Cu(OAc)2·H2O as the catalyst. High yields and good enantioselectivities (up to

A general one-step synthesis of β-nitronitriles
(Chemical Equation Presented) The unusual β-nitronitrile functionality was prepared by a simple one-step Kydrocyanation of nitroalkenes. These compounds were shown to be precursors to monoprotected 1,3-diamines and 1,3-amino alcohols through the in situ f

Method of producing organic compounds in presence of oxyethylene ether catalyst and in a solvent minimized environment
A process of producing organic compounds, such as acetaminophen, nitroalcohols and indoles, employs a catalyst system of an oxyethylene ether and a metal containing inorganic or organic reagent. The oxyethylene ether at least partially complexes the metal of the inorganic or organic reagent. As such, the reactions may be conducted neat. The processes are environmentally friendly and operationally simple.

Use of heterogeneous catalyst KG-60-NEt2 in Michael and Henry reactions involving nitroalkanes
The N,N-diethylpropylamine supported on amorphous silica (KG-60-NEt2) catalyses the formation of carbon-carbon bonds by nitroalkanes through both the nitroaldol (Henry) and Michael reactions. The catalyst shows general utility with a variety of electrophilic acceptors. Moreover, the catalyst can be reused for two further cycles without loss of the activity.

PREPARATION AND OXIDATION OF α-NITRO ALCOHOLS WITH SUPPORTED REAGENTS.
Preparation of 2-nitro alkanols has been achieved by condensation of aldehydes with nitroalkanes in the presence of alumina-supported potassium fluoride.Nitroketones are produced by oxidation of nitroalkanols with montmorillonite - supported chromium trioxide.
