Recent synthetic applications of α-amido sulfones as precursors of N-acylimino derivatives

Organic Chemistry Frontiers, 2019
α-Amido sulfones can be directly used as N-acylimine or N-acyliminium ion precursors in several synthetic processes aimed at the preparation of nitrogen containing compounds.

Asymmetric Conjugate Addition of Ethylene Sulfonyl Fluorides to 3-Amido-2-oxindoles: Synthesis of Chiral Spirocyclic Oxindole Sultams.

Organic Letters, 2019
An enantioselective conjugate addition of ethylene sulfonyl fluorides to 3-amido-2-oxindoles has been developed. Quinine-derived squaramides were identified as efficient catalysts.

Amido Phosphine Complexes of Zinc

Inorganic Chemistry, 2003
The first examples of amido phosphine complexes of zinc have been prepared. Addition of N-(2-diphenylphosphinophenyl)-2,6-diisopropylaniline (H[NP]) to ZnMe(2) or ZnEt(2) in diethyl ether at -35 degrees C generated the monomeric, three-coordinate [NP]ZnR (R = Me, Et), while the metathesis reaction of ZnCl(2) with [NP]Li(THF)(2) in diethyl ether at -35 ...

Multiple States of Dimeric Aggregates Formed by (Amido–ethynyl)helicene Bidomain Compound and (Amido–ethynyl–amido)helicene Tridomain Compound

Chemistry – A European Journal, 2012
AbstractAn (amido–ethynyl)helicene bidomain compound and an (amido–ethynyl–amido)helicene tridomain compound were synthesized. The multidomain compounds were designed on the basis of previous findings that amido and ethynyl oligomers form dimeric aggregates with properties orthogonal to each other. Four aggregate states of multidomain compounds, namely,

Nickel-Catalyzed Highly Enantioselective Hydrogenation of β-Acetylamino Vinylsulfones: Access to Chiral β-Amido Sulfones.

Organic Letters, 2018
The nickel/( S)-Binapine complex was found to be an efficient catalyst for asymmetric hydrogenation of β-acetylamino vinylsulfones to afford chiral β-Amido sulfones with excellent yields and enantioselectivities (up to 95% yields and >99% ee).

Asymmetric Mannich Reaction and Construction of Axially Chiral Sulfone-Containing Styrenes in One Pot from α-Amido Sulfones Based on the Waste-Reuse Strategy.

Organic Letters, 2018
A simultaneous asymmetric Mannich reaction and the construction of axially chiral sulfone-containing styrenes in one pot from α-amido sulfones based on the waste-reuse strategy was demonstrated.

Synthesis and Reactivity Studies of Amido-Substituted Germanium(I)/Tin(I) Dimers and Clusters.

Chemistry, 2018
Three amide ligands of varying steric bulk and electronic properties were utilized to prepare a series of amido-germanium(II)/tin(II) halide compounds, (LEX)n , (L= -N{B(DipNCH)2 }(SiMe3 ), TBo L; -N{B(DipNCH)2 }(SiPh3 ), PhBo L; -N(Dip)(tBu), DBu L; Dip=

Lithium Dimethyl(amido)zinc Complexes:  Contrasting Zincate (Amido = TMP) and Inverse Zincate (Amido = HMDS) Structures on Addition of TMEDA

Organometallics, 2006
Introducing TMEDA to the lithium dimethyl(amido)zincates “LiZn(NR2)Me2” leads to a discrete ion-contacted zincate with TMEDA bound to lithium in the case of NR2 = TMP but to a novel “inverse zincate” with TMEDA bound to zinc in the case of NR2 = HMDS, where unexpectedly Me2Zn(TMEDA) functions as a η1,μ ligand to dimeric (LiHMDS)2 molecules to afford a ...

Lanthanon(III) Amido Complexes

Synthesis and Reactivity in Inorganic and Metal-Organic Chemistry, 1981
Abstract Ln(NHCOR)3 (I) and Ln(SCNHCH3)3 (II) are prepared and characterized by elemental analysis, electronic and infrared spectra (Ln = La, Pr, Nd, Sm; R = CH3, C6H5, C5H4N). The bonding of matal to amide is through nitrogen in I while it is through sulphur in II.
