Selective Catalytic B-H Arylation of o-Carboranyl Aldehydes by a Transient Directing Strategy.

Journal of the American Chemical Society, 2017
Carboranyl aldehydes are among the most useful synthons in derivatization of carboranes. However, compared to the utilization of carboranyl carboxylic acids in selective B-H bond functionalizations, the synthetic application of carboranyl aldehydes is ...

Catalytic C-H Arylation of Aliphatic Aldehydes Enabled by a Transient Ligand.

Journal of the American Chemical Society, 2016
The direct arylation of aliphatic aldehydes has been established via Pd-catalyzed sp3 C-H bond functionalization in the presence of 3-aminopropanoic acids as transient directing groups.

C-O Functionalization of α-Oxyboronates: A Deoxygenative gem-Diborylation and gem-Silylborylation of Aldehydes and Ketones.

Journal of the American Chemical Society, 2017
A deoxygenative gem-diborylation and gem-silylborylation of aldehydes and ketones is described. The key for the success of this transformation is the base-promoted C-O bond borylation or silylation of the generated α-oxyboronates.

Iron Catalyzed Hydroboration of Aldehydes and Ketones.

Journal of Organic Chemistry, 2017
We report an operationally convenient room temperature hydroboration of aldehydes and ketones employing Fe(acac)3 as precatalyst. The hydroboration of aldehydes and ketones proceeded efficiently at room temperature to yield, after work up, 1° and 2 ...

Chemoselective Reduction of Tertiary Amides under Thermal Control: Formation of either Aldehydes or Amines.

Angewandte Chemie, 2016
The chemoselective reduction of amides in the presence of other more reactive reducible functional groups is a highly challenging transformation, and successful examples thereof are most valuable in synthetic organic chemistry.

E-cigarettes generate high levels of aldehydes only in 'dry puff' conditions.

Addiction, 2015
BACKGROUND AND AIMS Aldehydes are emitted by electronic cigarettes due to thermal decomposition of liquid components. Although elevated levels have been reported with new-generation high-power devices, it is unclear whether they are relevant to true ...

One-Pot Amide Bond Formation from Aldehydes and Amines via a Photoorganocatalytic Activation of Aldehydes.

Journal of Organic Chemistry, 2016
A mild, one-pot, and environmentally friendly synthesis of amides from aldehydes and amines is described. Initially, a photoorganocatalytic reaction of aldehydes with di-isopropyl azodicarboxylate leads to an intermediate carbonyl imide, which can react ...

Derivatization Strategy for the Comprehensive Characterization of Endogenous Fatty Aldehydes Using HPLC-Multiple Reaction Monitoring.

Analytical Chemistry, 2016
Fatty aldehydes are crucial substances that mediate a wide range of vital physiological functions, particularly lipid peroxidation. Fatty aldehydes such as acrolein and 4-hydroxynonenal (4-HNE) are considered potential biomarkers of myocardial ischemia ...
