A versatile and efficient method for the preparation of (2S)-2-(hydroxymethyl)-N-Boc-2,3-dihydro-4-pyridone from l-(−)-phenylalanine 2 utilising the aromatic system as a masked β-keto aldehyde was developed. The key step in the sequence is an intramolecular cyclisation of 6 to give 2,3-dihydropyridin-4-ones.
一种利用芳族体系作为掩盖的β-基由L-(-)-苯丙氨酸2制备(2 S)-2-(羟甲基)-N -Boc-2,3-二氢-4-吡啶酮的通用有效方法-酮醛被开发出来。序列中的关键步骤是6的分子内环化反应,得到2,3-二氢吡啶-4-酮。
