The first cascade diastereoselective synthesis of oxazoloisoindolinones via the palladium-catalyzed decarboxylative ortho-acylation of N-benzoyl α-amino acid derivatives followed by double intramolecular cyclizations has been demonstrated. This reaction, using α-amino acids as directing groups and α-oxocarboxylic acids as the acylation source, features a broad substrate scope, good functional group
已经证明了通过N-苯甲酰基α-氨基酸衍生物的钯催化的脱羧正酰化,然后是双分子内环化,首次级联非对映选择性地合成了恶唑并异吲哚满酮。该反应以α-氨基酸为导向基团,α-氧代羧酸为酰化源,具有广泛的底物范围,良好的官能团耐受性,高区域选择性和出色的非对映选择性。
