Abstract
We report a sequential catalytic asymmetric transfer hydrogenation-carboxylative cyclization for the facile construction of chiral 4-fluoroalkyl 2-oxazolidinones with high enantioselectivity. The resulting 2-oxazolidinones can be easily elaborated to synthetic useful chiral β-fluoroalkyl β-amino alcohols. This research also represents a rare example of catalytic asymmetric sequential reactions using CO2 as a C1 synthon as well as carboxylative cyclization of α-fluoroalkyl propargylamines.

Abstract
A straightforward synthesis of enantiopure α-trifluoromethyl aziridine-2-carboxylic acid (α-TfmAzy) is reported from a trifluoropyruvate derived enantiopure oxazolidine. A key Strecker-type synthetic step and a late cyanide basic hydrolysis gave the target compounds in six steps and 41% yield. A final peptide coupling was performed to demonstrate the usefulness of this highly constrained fluorinated unnatural amino acid.

Abstract
An enantioselective Strecker reaction to construct trifluoromethylated quaternary stereocenters with N-PMP and unexplored N-Boc trifluoromethyl ketimines catalyzed using an organophosphine dual-reagent catalyst has been developed. The enantioselectivities of the corresponding products with the same catalyst could be switched by using different N-protecting groups (N-PMP or N-Boc). The trifluoromethyl amino nitriles were obtained in high yield and high enantioselectivity in a short time and could be easily converted to a variety of useful trifluoromethyl-containing compounds.

Abstract
While a series of carbo-mers of 1,3-cyclohexadienes was reported through the use of a specifically developed synthetic strategy, no example of their 1,4-regioisomers was known. Inspired by the methodology elaborated for the preparation of the 1,3-isomers, the synthesis of the first example of carbo-mer of 1,4-cyclohexadiene is presented. Comparison of physico-chemical properties of this first representative with those of the recently described 1,4-regioisomer, especially UV-vis absorption properties, is also addressed.

Abstract
This chapter describes state-of-the-art methods to prepare α-chiral amines by the addition of nonstabilized nucleophiles to imine derivatives. The first part of the chapter illustrates the most effective diastereoselective addition reaction (substrate controlled and chiral auxiliary based methods) whereas the second part focuses on catalytic asymmetric methods.
