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 ...
