A new method for the stereoselective synthesis of 3-aminoindan-1-ones from triflates of salicylic sulfinyl imines and ethylene glycol vinyl ether has been developed. The reaction sequence starts with a regioselective Heck reaction followed by stereoselective Lewis acid mediated annulation. Acidic cleavage of the sulfinamides produced pure (R)- and (S)-3-aminoindan-1-ones, which were successfully isolated
已开发了一种新的方法,该方法可从水杨酸亚磺酰基亚胺和乙二醇乙烯基醚的三氟甲磺酸酯中立体选择性合成3-氨基茚满-1-酮。该反应序列以区域选择性Heck反应开始,随后是立体选择性路易斯酸介导的环空反应。亚磺酰胺的酸性切割产生纯的(R)-和(S)-3-氨基茚满-1-酮,将其成功分离并掺入活性HIV-1蛋白酶抑制剂中。
