Amino-2-propanol structures can be obtained by addition to dibenzyl acetals of in situ generated dihalocarbenes using LTV (Low Valent Titanium). This methodology can be used to obtain adrenergic β-blockers with amino-2-propanol structure. Tetrahalomethane are the best dihalocarbene precursors. The yields obtained using halofluromethanes can be increased by addition of carbontetrachloride. A process that can imply halogen transfer may be proposed.
