, (2020)
A mild and efficient nucleophilic monofluoromethylation of α-amido sulfones with trifluoromethyl α-fluorinated arylsulfonyl gem-diols as new building blocks has been developed, which affords N-Boc monofluoromethyl aryl sulfones in good yields with appropriate 5:1 diastereomeric ratio.

A Tf2NH-catalyzed aza-Ferrier reaction of N,O-allenyl acetals was reported. This protocol provided various types of β-amino-α-methylene aldehydes as the products. The N,O-allenyl acetal substrates were easily prepared by base-induced isomerization of N,O-propargyl acetals with Triton B. The N,O-propargyl acetals were prepared from the corresponding aldehydes or lactams. Further synthetic applications of the products were also described.

Asymmetric functionalizations of α-sulfanyl cyclic ketones were realized via chiral phosphoric acid catalyzed enantioselective addition reactions with aldimines, azodicarboxylates and allenamides. A series of chiral organosulfur compounds possessing sulfur-containing tetrasubstituted stereocenters were accessed via these methods, with excellent regioselectivities and high stereoselectivities. (Figure presented.).
