cyclocondensation of β aryl heteroaryl methylaminoenones with thionyl chloride a facile general approach for the synthesis of 2 4 bis het aryl 5 het Aroylthiazoles
Tetrahedron Letters, 2013Co-Authors: Toreshettahally R Swaroop, H Ila, K S RangappaAbstract:An efficient, regioselective route to 2,4-bis(het)aryl-5(het)Aroylthiazoles has been developed by cyclocondensation of thionyl chloride with novel β-(het)arylmethylaminoenones which are readily accessible by the reaction of (het)arylmethylamines with 1,3-bis(het)arylmonothio-1,3-diketones. The method allows entry to 2,4,5-trisubstituted thiazoles, with full control for the introduction of either a (het)aryl Group at 2,4 positions or a (het)Aroyl Group at 5 position of the thiazole ring.

direct Aroylation of β cyclodextrin on the secondary hydroxyl face a convenient equilibrium dependent preparation of mono 3 Aroyl β cyclodextrin via c2 o Aroyl to c3 o Aroyl Group migration
Monatshefte Fur Chemie, 2012Co-Authors: Zhizhong Wang, Qing Huang, Shijie Wei, Lei Sun, Jing ChenAbstract:A new and convenient method is presented for the preparation of mono-3-O-benzoyl-β-cyclodextrin by direct regioselective benzoylation of β-cyclodextrin using N-benzoylimidazole in carbonate buffer solution. This process involved equilibrium-dependent C2-O-Aroyl to C3-O-Aroyl Group migration to improve the yield.
