Visible-light-mediated fluoroalkylation of isocyanides with ethyl bromofluoroacetates: unified synthesis of mono- and difluoromethylated phenanthridine derivatives.

Xiaoyang Sun et al.

Organic letters, 16(11), 2938-2941 (2014-05-23)

A practical and unified strategy has been described for the preparation of mono- and difluoromethylated phenanthridine derivatives using a visible-light-promoted alkylation and decarboxylation sequence from biphenyl isocyanides with ethyl bromofluoroacetate (EBFA) or ethyl bromodifluoroacetate (EBDFA). These reactions could be carried

Synthesis of 4-substituted 3,3-difluoropiperidines.

Riccardo Surmont et al.

The Journal of organic chemistry, 75(3), 929-932 (2010-01-07)

Synthetic strategies toward 4-substituted 3,3-difluoropiperidines were evaluated. 4-Alkoxymethyl- and 4-aryloxymethyl-3,3-difluoropiperidines were synthesized via 1,4-addition of ethyl bromodifluoroacetate to 3-substituted acrylonitriles in the presence of copper powder, followed by borane reduction of the cyano substituent, lactamization, and reduction of the lactam.

Enantioselective synthesis of α,α-difluoro-β-lactams using amino alcohol ligands.

Atsushi Tarui et al.

Organic & biomolecular chemistry, 12(33), 6484-6489 (2014-07-16)

A practical and highly enantioselective Reformatsky reaction of ethyl bromodifluoroacetate with imines using a cheap and commercially available amino alcohol ligand is described. A variety of α,α-difluoro-β-lactams were obtained in up to 74% yield with high enantioselectivity in excess of
