    Microbiological enantioselective synthesis of (S) and (R) 4-(p-anisyloxy)-3-hydroxybutyrates as new chiral building blocks for the synthesis of β-lactam antibiotics
    摘要:
    Both anantiomers of 4-p-anisyloxy-3-hydroxybutanoates 4 have been prepared in high e.e. by reduction of the corresponding beta-ketoesters or beta-ketocarboxylates with immobilized fermenting baker's yeast. the utility of these new chiral building blocks in the synthesis of pharmacologically important beta-lactam antibiotics has been demonstrated.

  • Chemoenzymatic route to β-blockers via 3-hydroxy esters

    phenoxy-2-propanol) were synthesized. Key step is the lipase-catalyzed kinetic resolution of rac-3-hydroxy esters either by O-acylation using vinyl acetate or by hydrolysis of the ester group. Both approaches were highly enantioselective (> 95 %ee) with E-values > 150 using lipase from Pseudomonas cepacia. The formal synthesis of (−)-(S)-propranolol was developed in subsequent steps.
    合成了对映体纯的β-阻滞剂(普萘洛尔,阿普洛尔和1-(异丙氨基)-3-对甲氧基-苯氧基-2-丙醇)。关键步骤是使用乙酸乙烯酯的O-酰化作用或酯基的水解,可实现rac -3-羟基酯的脂肪酶催化动力学拆分。两种方法均使用洋葱假单胞菌的脂肪酶对映体选择性高(> 95%ee),E值> 150 。在随后的步骤中开发了(-)-(S)-普萘洛尔的形式合成。

  • Rh-catalyzed intramolecular aromatic C–H insertion of α-diazo β-ketoesters: synthesis of 4-carbonyl chroman derivatives
    作者:Xiaolin Zhang、Mei Lei、Yi-Nan Zhang、Li-Hong Hu

    日期:2014.5
    A Rh-catalyzed intramolecular aromatic C–H insertion of α-diazo β-ketoesters was developed. This protocol offers a practical strategy for the synthesis of 4-carbonyl chroman derivatives with high yield and is compatible with a wide variety of substituents. Synthetic applications of the 4-carbonyl chroman were also demonstrated.
