A palladium(II)-catalyzed tandem cyclization reaction involving an intramolecular 1,2-aminoalkylation of N-4,6-dienyl β-keto amides has been developed. This process provides an efficient method for the rapid assembly of pyrrolizidines starting from linear substrates in moderate to good yields and high to excellent diastereoselectivities.
已经开发了涉及N -4,6-二烯基β-酮酰胺的分子内1,2-氨基烷基化的钯(II)催化的串联环化反应。该方法提供了一种有效的方法,用于从线性底物以中等到良好的产率以及从高到优异的非对映选择性快速组装吡咯烷核苷。
