A novel approach towards highly functionalized fluoroalkyl pyrazoles was developed by using fluoroalkyl amino reagents in combination with a variety of fluorinated ketimines. Tuneable introduction of fluoroalkyl groups in the 3- and 5-positions was possible by using vinamidinium intermediates or the corresponding enamino ketones after hydrolysis. These high-value building blocks can give rise to a large number of analogues for bioactivity screening and discovering new heterocyclic bioactive ingredients in various life science fields.

The use of TFEDMA, a fluoroalkyl amino reagent, for the difluoromethylation and difluoroacylation of arenes, heteroarenes, and C-H acidic compounds is reported. This approach allows for an efficient access to difluoromethylated products of high added value in good to excellent yields and with scale-up possibilities.

The classical Reformatsky reaction introduced for the first time in 1887 has been recognized as one among the most useful methods for C-C bond formation. Diastereoselective versions based on the use of chiral auxiliaries as well as enantioselective protocols using chiral ligands have been successfully developed during the last few years. This tutorial review highlights the main recent achievements (since 2004) in the diastereoselective Reformatsky reaction; diastereochemical control has been efficiently achieved using a large variety of chiral auxiliaries to perform the synthesis of specific cyclic and acyclic chiral moieties.
