Intramolecular homolytic substitution (SHi) on the sulfur atom at acyclic N-(o-bromobenzyl)sulfinamides takes place with a complete inversion of the configuration and provides an excellent tool to connect N-tert-butanesulfinylimines with enantiopure 3-substituted benzo-fused sulfinamides (1,2-benzoisothiazoline 1-oxides) and the related pharmacologically relevant sulfonamides.

[reaction: see text] Palladium-catalyzed coupling reaction of N,N-dimethylformamide with aryl or alkenyl halides successfully proceeded in the presence of phosphoryl chloride to afford the corresponding tertiary amides in good yields.

This work describes the syntheses and antitumoral properties of five prenyl compounds from which antiproliferative activities were predicted by using the TOPS-MODE approach, a computational method for drug design. The syntheses of 2-(3-methylbut-2-enyloxy)acetophenone (2), 2-hydroxy-5-(3-methylbut-2-enyl)acetophenone (3), 2-hydroxy-3-(1,1-dimethylallyl)acetophenone (4), and 5-(3-methylbut-2-eny...

Upon illumination of spinach chloroplasts in the presence of [32P]orthophosphate and AMP and absence of substrate ADP, coupling factor-bound [32P]ADP is formed. This bound r3’P]ADP is stable enough to withstand purification of the coupling factor to homogeneity. However, the ability of this specially bound [““PIADP to serve as the ultimate phosphoryl donor to substrate ADP for the synthesis of ...

Organocatalysts have attracted enormous interest in the water-crosslinking reaction in silane-grafted polyolefins (SGPOs) system owing to their simplicity, low toxicity and environmentally benign nature compared to organotin catalysts, which are most used in SGPOs system. We focus on organophosphorus compounds including four structure types as organocatalysts; phosphoric acids, phosphoric ester...

While investigating the enzymatic conversion of n-glyceric acid-3phosphoric acid to pyruvic acid and phosphoric acid, an essential step both in glycolysis and fermentation, Meyerhof and Lohmann (1) observed the formation of a hitherto unknown organic phosphoric acid ester. They succeeded in isolating the new intermediary compound by virtue of the ease of crystallization of the silver-barium sal...
