Reaction of carbohydrates with Vilsmeier reagent: a tandem selective chloro O-formylation of sugars.
A convenient and efficient method for selective replacement of the primary hydroxyl groups of sugars by chlorine with concomitant O-formylation, compatible with the presence of a variety of functional groups, has been developed using the Vilsmeier-Haack reaction. Sugars having free primary hydroxyl groups mostly afforded the chloro-O-formylated product while sugars devoid of primary hydroxyl gr...
متن کاملSynthesis of benzaldehyde substituted phenyl carbonyl hydrazones and their formylation using Vilsmeier-Haack reaction
A series of benzaldehyde substituted phenyl carbonyl hydrazones has been synthesized and their formylation has been carried out by using Vilsmeier-Haack reaction. All the hydrazones and their formyl derivatives were screened for antibacterial activity.
متن کاملFormylation of amines.
Methods to convert amines to formamides are of interest due to the many uses of formamides as synthetic intermediates. These methods include stoichiometric reactions of formylating reagents and catalytic reactions with CO as the carbonyl source. This review discusses the reported stoichiometric and catalytic approaches for preparation of formamides.
متن کاملSolid Phase Formylation of N-Terminus Peptides.
Formylation of amino groups is a critical reaction involved in several biological processes including post-translational modification of histones. The addition of a formyl group (CHO) to the N-terminal end of a peptide chain generates biologically active molecules. N-formyl-peptides can be produced by different methods. We performed the N-formylation of two chemotactic hexapetides, Met1-Leu2-Ly...
متن کاملFormylation of folate as step in physiological folate absorption.
Oral administration of folate analogues to rats is followed by a rise in plasma folate detectable only by micro-biological assay with Lactobacillus casei, suggesting methylation of folate during absorption. When using the everted rat gut technique with folate (PteGlu), dihydrofolate (H(2)PteGlu), or tetrahydrofolate (H(4)PteGlu) on the mucosal surface formyl folate (10-CHO-PteGlu, 10-CHO-H(4)Pt...
