Abstract
Synthesis of versatile β tert-boryl amides is accomplished by conjunctive cross-coupling of α-substituted alkenyl boron "ate" complexes and carbamoyl chloride electrophiles. This reaction can be accomplished in an enantioselective fashion using a palladium catalyst in combination with MandyPhos. The addition of water results in enhanced chemoselectivity for the conjunctive coupling product relative to the Suzuki-Miyaura cross-coupling product. Transformations of the reaction products were examined as well as application to the synthesis of (+)-adalinine.

Abstract
Using a commercially available, inexpensive, and abundant copper catalyst system, an efficient α-functionalization of nitroalkanes with propargyl bromides is now established. This mild and robust method is highly functional group tolerant and provides straightforward access to complex secondary and tertiary homopropargylic nitroalkanes. Moreover, the utility of these α-propargylated nitroalkanes is demonstrated through downstream functionalization to biologically relevant, five-membered N-heterocycles such as pyrroles and 2-pyrrolines.

Abstract
Background:
α-Aryl substituted nitroalkanes are important synthetic intermediates
for the preparation of pharmaceutical molecules, natural products, and functional
materials. Due to their scare existence in Nature, synthesis of these compounds has attracted
the attention of synthetic and medicinal chemists, rendering α-arylation of nitroalkanes
of an important research topic. This article summarizes the important advances of α-
arylation of nitroalkanes since 1963.
Results:
After a brief introduction of the synthetic application and the reactions of nitroalkanes,
this article reviewed the synthetic methods for the α-arylated aliphatic nitro compound.
The amount of research on α-arylation of nitroalkanes using various arylation reagents
and the discovery of elegant synthetic approaches towards such skeleton have been
discussed. This review described these advances in two sections. One is the arylation of non-activated nitroalkanes,
with an emphasis on the application of diverse arylation reagents; the other focuses on the arylation of
activated nitroalkanes, including dinitroalkanes, trinitroalkanes, α-nitrosulfones, α-nitroesters, α-nitrotoluenes,
and α-nitroketones. The synthetic application of these methods has also been presented in some cases.
Conclusion:
In this review, we described the progress of α-arylation of nitroalkanes. Although the immense
amount of research on α-arylation of aliphatic nitro compounds has been achieved, many potential issues still
need to be addressed, especially the asymmetric transformation and its wide application in organic synthesis.
