Putta, V. P. Rama Kishore; Gujjarappa, Raghuram; Tyagi, Ujjawal; Pujar, Prasad P.; Malakar, Chandi C. published the artcile< A metal- and base-free domino protocol for the synthesis of 1,3-benzoselenazines, 1,3-benzothiazines and related scaffolds>, Category: alcohols-buliding-blocks, the main research area is arylthiazinone preparation; benzoselenazine preparation; diaryldiazocine dione preparation; benzothiazine preparation.
Efficient protocols have been described for the synthesis of 1,3-benzoselenazines, 1,3-benzothiazines, 2-arylthiazin-4-ones and diaryl[b,f][1,5]diazocine-6,12(5H,11H)-diones. These transformations were successfully driven towards product formation under mild acid catalyzed reaction conditions at room temperature using 2-aminoaryl/hetero-aryl alkyl alcs. and amides as substrates. The merits of the present methods also rely on the easy access of rarely explored bioactive scaffolds like 1,3-benzoselenazine derivatives, for which well-documented methods are rarely known in the literature. A broad range of substrates with both electron-rich and electron-deficient groups were well-tolerated under the developed conditions to furnish the desired products in yields up to 98%. The scope of the devised method was not only restricted to the synthesis of 1,3-benzoselenazines, but it was further extended towards the synthesis of 1,3-benzothiazines, 1,3-benzothiazinones and the corresponding eight-membered N-heterocycles such as diaryl[b,f][1,5]diazocine-6,12(5H,11H)-diones.
