The unknown stereostructure of 2-amino-3-cyclopropylbutanoic acid 1, a novel plant growth regulator isolated from the mushroom Amanita castanopsidis Hongo, was determined to be (2S,3S)-2 through its racemic and enantioselective syntheses employing the chelate–enolate Claisen rearrangement as a key step.
2-amino-3-cyclopropylbutanoic acid 1 是一种从 Amanita castanopsidis Hongo 蘑菇中分离出来的新型植物生长调节剂,其未知的立体结构是 (2S,3S)-2,其外消旋和对映体选择性合成的关键步骤是螯合烯醇克莱森重排。
