Synthesis, Functionalization, and Reactivity of Vinyl Sulfondiimidamides
Angewandte Chemie, EarlyView.Combining unsymmetrical sulfurdiimide reagents (R‐NSN‐R1) and Grignard reagents, followed by oxidative amination, delivers a series of vinyl sulfondiimidamides. Reactivity with cysteine and lysine derivatives is shown, and the cysteine reactivity is mapped in detail. Variation of the two imidic N‐substituents can be used to tune reactivity of these new

Unusual structure-energy correlations in intramolecular Diels–Alder reaction transition states [PDF]
, 2014 Detailed analysis of calculated data from an experimental/computational study of intramolecular furan Diels–Alder reactions has led to the unusual discovery that the mean contraction of the newly forming C-C σ-bonds from the transition state to the ...

Catalytic enantioselective synthesis of quaternary carbon stereocentres. [PDF]
, 2014 Quaternary carbon stereocentres-carbon atoms to which four distinct carbon substituents are attached-are common features of molecules found in nature. However, before recent advances in chemical catalysis, there were few methods of constructing single ...

Network-analysis-guided synthesis of weisaconitine D and liljestrandinine. [PDF]
, 2015 General strategies for the chemical synthesis of organic compounds, especially of architecturally complex natural products, are not easily identified. Here we present a method to establish a strategy for such syntheses, which uses network analysis.

An ab initio study of the mechanism of the cycloaddition reaction forming bicyclic compounds between vinylidene (H2C=C:) and ethylene [PDF]
Journal of the Serbian Chemical Society, 2011 The mechanism of the cycloaddition reaction forming a bicyclic compounds between singlet vinylidene (H2C=C:) and ethylene was investigated using the CCSD(T)//MP2/6-31G* method. From the potential energy profile, it can be predicted that this reaction has

[2+2]-cycloadditions of alkenes with the triphenylallenyl cation [PDF]
, 1984 The triphenylallenyl cation (8), generated from triphenylpropynol (7) and FSO3H, reacts with alkenes to give the allyl cations 12, which may be deprotonated to yield the methyleneccylobutenes 14.
