The title amino acid (2) has been synthesized for the first time in a seven-step sequence from -ribonolactone, in 20% overall yield. Since the -carbamoyl derivative of (2) in its γ-lactone form has been used to prepare clavalanine, a formal total synthesis of this antibiotic is derived.
标题氨基酸(2)首次以7个步骤从-ribonolactone合成,总收率为20%。由于已经使用了以其γ-内酯形式的(2)的-氨基甲酰基衍生物制备了卡瓦拉宁,因此得到了该抗生素的正式全合成。
