Note on the Preparation of L-α,γ-Diaminobutyric Acid

Abstract
In our laboratory we needed L-α,γ-diaminobutyric acid and we successfully tried to improve the method of Adamson (1) (scheme 1). As there are many articles in the literature dealing with the synthesis of this compound (sometimes making use of tedious isolation procedures and leading to yields ranging from 15 to 62% (2–8)), it appeared useful to describe our method.
