Highly enantioselective conjugate addition of fluoromalonates to nitroalkenes using bifunctional organocatalysts

Enantioselective Organocatalytic Synthesis of Fluorinated Molecules

“…Some months later, Kim and co‐workers37 published the same reaction catalyzed by a bifunctional organocatalyst derived from BINOL ( XVI ), obtaining also similar good results.…”

Enantioselective Michael addition of 2-hydroxy-1,4-naphthoquinones to nitroalkenes catalyzed by binaphthyl-derived organocatalysts

“…In the framework of our research program for the development of synthetic methods for the enantioselective construction of stereogenic carbon centers [ 37 – 42 ], we recently reported the enantioselective Michael addition of active methines to nitroalkenes [ 43 – 44 ]. Herein, we describe the direct enantioselective Michael addition of 2-hydroxy-1,4-naphthoquinone with nitroalkenes, catalyzed by bifunctional organocatalysts ( Fig.…”

Enantioselective Michael Addition of 3-Aryl-Substituted Oxindoles to Methyl Vinyl Ketone Catalyzed by a Binaphthyl-Modified Bifunctional Organocatalyst

“…As part of the research program related to the development of synthetic methods for the catalytic carbon-carbon bond formations [ 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 ], we recently reported the organocatalytic conjugate addition reactions of α,β-unsaturated carbonyl compounds [ 51 , 52 , 53 ] and other Michael acceptors [ 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 , 65 , 66 , 67 , 68 ]. In this Communication, we wish to describe the enantioselective conjugate addition reaction of 3-substituted oxindoles with methyl vinyl ketone catalyzed by binaphthyl-modified bifunctional organocatalysts bearing both central and axial chiral elements.…”
