Aldehyde deformylation is one of the useful reactions in biology and organic syntheses this review provides mechanistic insights into same.

Significance: Aldol reactions in which the aldol donor is derived from an aldehyde, are particularly challenging. This report describes a strategy in which aldehyde enolates are generated in situ by rhodium-catalyzed isomerization of triallylboroxanes. High syn-selectivity is obtained for a variety of aldehyde-donor and -acceptor partners. Comment: Remarkably, the use of triallyloxyboranes is n...

A highly enantioselective rhodium-catalyzed allylic alkylation of prochiral α,α-disubstituted aldehyde enolates with allyl benzoate is described. This protocol provides a novel approach for the synthesis of acyclic quaternary carbon stereogenic centers and it represents the first example of the direct enantioselective alkylation of an aldehyde enolate per se. The versatility of the α-quaternary...

Abstract A set of C 3 N 4 samples has been prepared by using melamine, cyanuric acid and barbituric as the precursors. The materials were subjected both to physical chemical characterization used photocatalysts for selective oxidation aromatic alcohols in water suspension under UV visible irradiation. photoactivity versus partial four substituted benzyl was investigated. type position substitue...

Attempts to obtain experimental values for the kinetic parameters of phenanthridine oxidation by guinea pig or rabbit liver aldehyde oxidase using common spectrophotometric methods have not been successful due to a lower limit of detection. In the present study, a new spectrofluorimetric assay in combination with a multivariate calibration method for enzymatic kinetic study of aldehyde oxidase ...

one pot solvent less synthesis of amidoalkylnaphthol derivatives via reaction of aldehydes, 2-naphthol and acetamide/urea in the presence of phenylphosphinic acid is  described. this methodology provides a simple synthetic route to amidoalkylnaphthols in good to high yields.

Aldehyde dehydrogenase from the bioluminescent bacterium, Vibrio harveyi, catalyses the oxidation of long-chain aliphatic aldehydes to acids. The enzyme is unique compared with other forms of aldehyde dehydrogenase in that it exhibits a very high specificity and affinity for the cofactor NADP(+). Structural studies of this enzyme and comparisons with other forms of aldehyde dehydrogenase provid...

Aldehydes-induced toxicity has been implicated in many neurodegenerative diseases. Exposure to reactive aldehydes from (1) alcohol and food metabolism; (2) environmental pollutants, including car, factory exhausts, smog, pesticides, herbicides; (3) metabolism of neurotransmitters, amino acids and (4) lipid peroxidation of biological membrane from excessive ROS, all contribute to 'aldehydic load...
