The Baylis-Hillman reaction: a new continent in organic chemistry: Our philosophy, vision and over three decades of research

26-Jun-2018 | Deevi Basavaiah; Ram Tilak Naganaboina, New Journal of Chemistry, 2018

This review describes, in brief, the philosophy, vision and long research experience of the senior author (DB) in the area of Baylis-Hillman (BH) [also known as Morita-Baylis-Hillman (MBH)] reaction. It presents a clear picture how the senior author (DB) has, i) uncovered BH reaction which was ...

Making a triple negative

22-Jun-2018 | Sacha Vignieri; Jesse Smith; Jake Yeston, Science , 2018

Organic Chemistry The trifluoromethanesulfonyl (Tf) group is remarkably adept at stabilizing negative charge: It boasts highly withdrawing fluorines and sulfur-oxygen bonds that can delocalize electrons through resonance. Höfler et al. took full advantage of these properties in generating a

The predictive power of aromaticity: quantitative correlation between aromaticity and ionization potentials and HOMO–LUMO gaps in oligomers of benzene, pyrrole, furan, and thiophene

05-Jun-2018 | Renana Gershoni-Poranne; Anuja P. Rahalkar; Amnon Stanger, Physical Chemistry Chemical Physics, 2018

Aromaticity is a central and ubiquitous concept in organic chemistry, and is used extensively to explain various phenomena. Yet, aromaticity cannot be observed or measured as a property in its own right and, to date, only qualitative and semi-quantitative relationships have been described between ...

Arenes get a light boost onto copper

01-Jun-2018 | Caroline Ash; Jake Yeston, Science , 2018

Organic Chemistry Insertion of palladium into an aryl halide bond is the first step in numerous variants of cross-coupling chemistry used to make carbon-carbon bonds. Copper is an appealing alternative catalyst for such reactions because of its abundance and downstream reactivity profile. However,

Total synthesis of complex terpenoids employing radical cascade processes

27-May-2018 | Kevin Hung; Xirui Hu; Thomas J. Maimone, Natural Product Reports, 2018

Covering: 2011–2017 Radical cyclizations have a rich history in organic chemistry and have been particularly generous to the field of natural product synthesis. Owing to their ability to operate in highly congested molecular quarters, and with significant functional group compatibility, ...

Assessment of the electron donor properties of substituted phenanthroline ligands in molybdenum carbonyl complexes using molecular electrostatic potentials

27-May-2018 | Geetha S. Remya; Cherumuttathu H. Suresh, New Journal of Chemistry, 2018

The relevance of substituent effects in the design and development of novel molecules has considerable interest in many industrial and synthetic reactions in organic chemistry. Molecular electrostatic potential (MESP) parameters are found to be excellent descriptors for characterizing the ...

Advances in heterocycle synthesis via [3+m]-cycloaddition reactions involving an azaoxyallyl cation as the key intermediate

27-May-2018 | Jun Xuan; Xia Cao; Xiao Cheng, Chemical Communication, 2018

Heterocyclic compounds are widely found in many natural isolates and medicinally relevant compounds, as well as some fine chemicals. The development of general and efficient methods for the construction of heterocyclic compounds is one of the most important tasks in synthetic organic chemistry. ...

Beyond geminal diesters: increasing the scope of metal-mediated vinylcyclopropane annulations while decreasing pre-activation

26-May-2018 | Duncan K. Brownsey; Evgueni Gorobets; Darren J. Derksen, Organic & Biomolecular Chemistry, 2018

The utilization of unactivated substrates in annulation reactions provides access to complex products without the need for subsequent removal of the activating group. Vinylcyclopropanes (VCPs), occurring naturally in several monoterpene natural products, are an important building block for ...

Stereoselective arene formation

26-May-2018 | Achim Link; Christof Sparr, Chemical Society Reviews, 2018

While aromatic hydrocarbons are ubiquitous in organic chemistry, they are typically not associated with chirality and stereoisomerism. Due to the planarity and symmetry of simple arenes, methods to assemble aromatic rings are not routinely considered for the stereoselective synthesis of chiral ...
