catalysts based on Al2O3, supercritical carbon dioxide not only acts as a good solvent for the reaction of aromatic and aliphaticaldehydes with 1-nitroalkanes but, most importantly, it also allows the selectivity to be tuned between the competitive formation of beta-nitroalcohols and nitroalkenes (from the Henry reaction and the nitroaldol condensation, respectively). In particular, when the pressure

Pyrroles havinglongalkylchains at the 3-and/or 4-positions are readily prepared by the reaction of ethyl isocyanoacetate with nitroalkenes havinglongalkylchains.
Disclosed herein are oxiran amines useful for the treatment of a variety of diseases. The oxiran amines are useful in the manufacture of pharmaceutical compositions. The pharmaceutical composition may be used for the treatment or prevention of a disease caused by a virus having a lipid membrane or the pharmaceutical composition may be used for diseases requiring cell proliferation or immune-regulation.
