Abstract
We present a short and efficient synthesis of the title compounds starting with cheap and readily available camphor and derivatives of acetophenone. The optimized sequence allows the large-scale preparation of this new type of synthesis in a few steps. New 1,2,3-thiadiazole and 1,2,3-diazaphosphole derivatives 11-20, were prepared from the ketones 1-5 via the corresponding semicarbazones 6-10. The Hurd-Mori and Lalezari methods were used, respectively, for the preparation of these 1,2,3-thiadiazole and 1,2,3-diazaphospholene derivatives. These derivatives exhibit anticancer effect due to their high potential biological activity.
