The salts of α-bromo acids react gently with imines in tetrahydrofuran in the presence of zinc; after acid hydrolysis, β-amino acids are directly obtained.

Abstract The ZnBr2 promoted addition of ketene bis(trimethylsilyl) acetals to aromatic aldimines affords β-arylaminoacids in good to excellent yields. Under the same reaction conditions vinylic ketene bis(trimethylsilyl) acetals give exclusively or mainly δ - phenylaminoacids.
