Synthesis of Acetals Containing a Primary Amino Group

Lobanova,Stankevich,Kukharev

, p. 1289 - 1296 (2013/02/21)

Amino acetals of the general formula MeCH(OR)(OXNH2) (R = Et, Bu, X = CH2CH2, CH2CH2CH 2, CH2CMe2) were synthesized in 53-91% yield by acid-catalyzed reaction of N-(2-hydroxyethyl)-, N-(3-hydroxypropyl)-, and N-(2-hydroxy-1,1-dimethylethyl)-2,2,2-trifluoroacetamides with vinyl ethers, followed by removal of the trifluoroacetyl protection by alkaline hydrolysis.
