A method for producing a β-alkoxypropionamide including:
subjecting a β-alkoxypropionic acid ester represented by the following formula (I) and a polyol having two or more OH groups to a transesterification reaction in the presence of a basic catalyst, thereby to synthesize a transesterified polyol of a β-alkoxypropionic acid ester; and
subjecting the transesterified polyol and an amine represented by the following formula (II) to an amidation reaction, thereby to synthesize a β-alkoxypropionamide represented by the following formula (III):

We describe an efficient method for the synthesis of aminocyclobutanes via a [2 + 2] cycloaddition between a keteniminium salt and an alkene, followed by a reduction step. The use of easily removable N-allyl moieties as protecting groups increases the potential of this method to access, in a few steps, highly functionalized cyclobutaneamine-containing building blocks. Moreover, DFT calculations verify

Disclosed herein are a reaction method and a production method of an organic compound which are capable of achieving high reaction selectivity according to the purpose and a high production rate of a target substance. The methods include at least two fluids, wherein at least one kind of the fluids is a fluid containing at least one organic compound and at least one kind of the fluids other than the above fluid is a fluid containing at least one reactant in the form of a liquid or solution, and the respective fluids join together in a thin film fluid foamed between processing surfaces arranged to be opposite to each other so as to be able to approach to and separate from each other, at least one of which rotates relative to the other, whereby an organic reaction is performed in the thin film fluid.

Alterations of certain metabolite concentrations and fluxes that occur in response to viral infection are described. Host cell enzymes in the involved metabolic pathways are selected as targets for intervention; i.e., to restore metabolic flux to disadvantage viral replication, or to further derange metabolic flux resulting in “suicide” of viral-infected cells (but not uninfected cells) in order to limit viral propagation. While any of the enzymes in the relevant metabolic pathway can be selected, pivotal enzymes at key control points in these metabolic pathways are preferred as candidate antiviral drug targets. Inhibitors of these enzymes are used to reverse, or redirect, the effects of the viral infection. Drug candidates are tested for antiviral activity using screening assays in vitro and host cells, as well as in animal models. Animal models are then used to test efficacy of candidate compounds in preventing and treating viral infections. The antiviral activity of enzyme inhibitors is demonstrated.
