commonly encountered intermediates found in natural product synthesis and medicinal chemistry. However, because of high reactivity, instability, and harsh reaction conditions, they are difficult to synthesize. Herein we have developed an oxidation-free method to produce sulfinic acids and sulfinate salts using 2-sulfinyl benzothiazole (BTS). We have also demonstrated the synthetic usefulness by developing
亚磺酸是天然产物合成和药物化学中常见的中间体。然而,由于高反应性,不稳定性和苛刻的反应条件,它们难以合成。本文中,我们开发了一种使用2-亚磺酰基苯并噻唑(BTS)的无氧化方法来生产亚磺酸和亚磺酸盐。我们还通过开发一锅合成砜和磺酰胺证明了合成的有用性。
