Synthesis of dendrimers with terminal formyl groups

Bioactivity‐Guided Isolation of Anti‐Inflammatory Constituents of the Rare Mushroom Calvatia nipponica in LPS‐Stimulated RAW264.7 Macrophages

“…CESL was separated using the same method, where five alkaloids ( 1 – 5 ) and two phenolic compounds ( 6 and 7 ) were isolated. The isolated compounds were identified as N , N ‐dimethylanthranilic acid ( 1 ), N ‐(4‐hydroxyphenyl)acetamide ( 2 ), 2‐(methylamino)benzoic acid ( 3 ), nicotinamide ( 4 ), 2,3‐dihydro‐4,6‐dihydroxy‐1 H ‐isoindol‐1‐one ( 5 ), 5,7‐dihydroxyisobenzofuran‐1(3 H )‐one ( 6 ), 5‐(hydroxymethyl)‐1,3‐benzenediol ( 7 ), and (7 Z ,10 Z )‐7,10‐octadecadienoic acid methyl ester ( 8 ) by comparison of spectroscopic and LC/MS data with the reported values ( Figure ). To the best of our knowledge, this study reports the identification of compound 8 for the first time from C .…”

Pentafluorobenzaldehyde and its utilizing in organic synthesis

“…Many publications and patents have reported preparations of magnetic and conductive polymers and functionalized copolymers [37][38][39][40][41][42][43][44][45][46][47][48][49], dendrimers [50,51], dyes [52,53] and chemiluminiscent materials too [54]. Other interesting data such as molecular polarizability, energies, electrochemical properties, half-time of fluorescence or phosphorescence, etc., have been reported too .…”

Functionalised bicyclic tetramates derived from cysteine as antibacterial agents

“…J-coupling constant of the anomeric C-H. Aryl glycosylation gave aldehyde 20c, which was condensed with ʟ-cysteine methyl ester hydrochloride, acylated and cyclised to afford tetramate 21.Due to the acid-labile nature of phenyl glycosides prepared above and the resulting difficulty associated with the acidic work-up procedure required to remove chelating metal ions, an alternative route to the incorporation of glycones via a benzyl alcohol linking group was explored (Scheme 8).The controlled reduction of terephthalaldehyde with NaBH 4 between 0-2°C afforded 4-(hydroxymethyl)benzaldehyde in 70 % yield according to a modified literature procedure 52. Lewis acid-catalysed glycosylation with β-D-galactosepentaacetate 15a gave aldehyde 22 as the β-anomer in 71% yield along with the byproduct 4-(acetoxymethyl)benzaldehyde in 28 % yield.…”
