Microwave-Assisted Synthesis of 2-Substituted 2-Thiazolines and 5,6-Dihydro-4 H -1,3-thiazines

An efficient and general method for the synthesis of 2-substituted thiazolines and 5,6-dihydro-4 H -1,3-thiazines is developed via microwave-assisted ring closure of omega -thioamidoalcohols promoted by ethyl polyphosphate (PPE). The cyclization reaction involves an S (N) 2-type mechanism and features the advantages of very short reaction times, high yields and a predictable stereochemical outcome. The acyclic precursors are prepared in high overall yields by an improved diacylation-thionation-saponification sequence from commercially available omega -aminoalcohols. The whole process is metal-free and operationally simple.

SERS Spectroscopy and DFT Studies of Thionine and its Derivatives Adsorbed on Silver Colloids: Which N Atom is Used for Coordination of a Phenothiazine-Based Natural Dye to Electron-Deficient Metal Surface?

A Surface-enhanced Raman scattering (SERS) investigation has been carried out for thionine and its derivatives, well known blue-based dyes sharing the phenothiazine core. The thionine SERS spectrum is similar to its Raman spectrum. This suggests that the strong Raman bands mostly arising from in-plane ring modes are also enhanced on metal surface. Several originally weak Raman bands arising from the CNC moiety or H atoms on the thiazine N side also largely strengthen in the SERS spectrum. Density functional theory results for the plausible coordinated structures of thionine and the silver adatom reveal that coordination via the thiazine N atom to Ag+ leads to the most stable structure, and its calculated spectrum also best reproduces the SERS spectrum. The thionine derivatives show surprisingly analogous spectra, reflecting that the derivatives coordinate in a similar fashion to the metal surface. The high preference of the thiazine N atom for coordination is traced to the positive charge on the S atom.

A stereoselective thiocyanate conjugate addition to electron deficient alkynes and concomitant cyclization to N, S-heterocycles

A regio- and stereoselective thiocyanate addition to ynones is achieved using KSCN in AcOH at 70 degrees C. The reaction is extendable to ynals, ynesulfones, ynoic acids and ynoates. Adducts from ynones were readily transformed into thiazine-2-thione derivatives under slightly modified reaction conditions. In contrast, thiocyanated adducts from ynamides underwent an in situ decyanative amido cyclization towards isothiazolones. None of these events needed any transition metal or catalyst, attaining a high synthetic value.
