TCFH itself is a common reagent used in the preparation of uronium and guanidinium salts used for amide bond formation and peptide synthesis, such as HATU. [3] [4] [5]Amide bond formation with TCFH can be performed in a wide range of organic solvents, most commonly acetonitrile, but also water [6] and in the solid state. [7]
Both authors also reduced the nitro group to an amine functionality using Raney Nickel. Up until this point, all of the nitro-Mannich methodologies reported had used imines that were formed in situ from an aldehyde and an amine. In 1950, Hurd and Strong reported [12] the first nitro-Mannich reaction using a preformed imine. Exposing an imine to ...
HATU is commonly encountered in amine acylation reactions (i.e., amide formation). Such reactions are typically performed in two distinct reaction steps: (1) reaction of a carboxylic acid with HATU to form the OAt-active ester; then (2) addition of the nucleophile (amine) to the active ester solution to afford the acylated product.

Among the producers of Michael are co-executors of the Jackson estate John Branca and John McClain. The film also stars the singer's real-life nephew Jaafar Jackson, 28, in the lead role.
The Stork enamine alkylation involves the addition of an enamine to a Michael acceptor (e.g., an α,β -unsaturated carbonyl compound) or another electrophilic alkylation reagent to give an alkylated iminium product, which is hydrolyzed by dilute aqueous acid to give the alkylated ketone or aldehyde.
