Amino-2-propanol structures can be obtained by addition to dibenzyl acetals of in situ generated dihalocarbenes using LVT (Low Valent Titanium). This methodology can be used to obtain adrenergic β-blockers with amino-2-propanol structure. Tetrahalomethanes are the best dihalocarbene precursors. The yields obtained using halofluoromethanes can be increased by addition of carbontetrachloride. A process
氨基-2-丙醇结构可通过使用LVT(低价钛)加入原位生成的二卤卡宾的二苄基乙缩醛中获得。该方法可用于获得具有氨基-2-丙醇结构的肾上腺素β-受体阻滞剂。四卤甲烷是最好的二卤卡宾前体。通过添加四氯化碳可以提高使用卤代氟甲烷获得的收率。可以提出可以暗示卤素转移的方法。
