out Willgerodt-Kindlerreaction of aromatic aldehydes at room temperature. At 120 °C, it is catalyst free reaction with lower reaction time whereas at room temperature, due to the additional amine molecule, Willgerodt-Kindlerreaction of aromatic aldehydes is successfully carried out at room temperature. On gram-scale, the reaction is successfully attempted under both conditions with good yields.

A method of selectively depleting pathogenic T lymphocytes from a blood cell composition is carried out by (a) combining the cell composition ex vivo with an active compound in an effective amount, and then (b) irradiating the cells with light ex vivo for a time and at an intensity sufficient to selectively kill pathogenic T lymphocytes in said cell composition. Chalcogenorhodamine photosensitizers useful as such active compounds are also described.

singlet oxygen, and were transported by P-glycoprotein (P-gp). To determine the selectivity of the photosensitizers in the ECP milieu, staphylococcal enterotoxin B (SEB)-stimulated and non-stimulated human lymphocytes were combined with HUT-78 cells (a CTCL) to simulate ECP. The amide-containing analogues of the selenorhodamines were transported more rapidly than the thioamideanalogues in monolayers of

We present a condensation of primary aryl or alkyl amines with S-methyl thiouronium salts to obtain N,N,N′-trisubstituted amidines. High yields, short reaction times, and a fair substrate scope are the noteworthy features of this protocol. Surprisingly, the reaction of a thiouronium salt with 4-aminopyridine gave 1-(4-methoxybenzoyl)piperidine.
我们提出了伯芳基胺或烷基胺与S-甲基硫脲盐的缩合以获得N , N , N'-三取代脒。高产量、短反应时间和公平的底物范围是该协议的显着特点。令人惊奇的是,硫脲盐与4-氨基吡啶的反应得到1-(4-甲氧基苯甲酰基)哌啶。

Benzotriazole reagents for thioacylation (RCSBt), thiocarbamoylation (RR'NCSBt), aryl/alkoxythioacylation (ROCSBt), and aryl/alkylthiothioacylation (RSCSBt) are synthesized, and their utility is assessed by syntheses of representative heteroaryl thioureas 3a-g, thioamides 15a-s, thionoesters 16a-h, thiocarbamates 17a-e, dithiocarbamates 18a-d, thiocarbonates 19a-c, and dithiocarbonates 20a-c.
