Paragraph 0027; 0038; 0047; 0048, (2017/08/29)
The invention discloses a synthetic method for N-substituent-3-aminoacrolein. The method comprises the following steps: with secondary amine and 3-chloroallyl alcohol as raw materials, and active manganese dioxide as a catalyst, carrying out introducing into an air environment, then carrying out a reaction at 0.5 to 2.5 MPa and 40 to 90 DEG C for 6 to 14 h, and after completion of the reaction, postprocessing a reaction solution so as to obtain an N-substituent-3-aminoacrolein derivative, wherein the yield is 68% to 97%. Compared with a conventional method for synthesizing the N-substituent-3-aminoacrolein, the method provided by the invention has the advantages of low toxicity, low pollution, simple operation, etc.

A highly enantioselective synthesis of (+)- and (-)-fluvastatin and their analogues has been facilitated by the reaction of an aldehyde with diketene in the presence of Ti(O-i-Pr)4 and a chiral Schiff base ligand. Either enantiomer of the Schiff base could be employed to obtain (+)- or (-)-fluvastatin. Diastereoselective reductions of the resultant keto moiety of β-hydroxy ketoesters provided the syn-1,3-diol esters (91% ee), which were subsequently recrystallized and saponified to afford (+)- and (-)-fluvastatin in >99.9% ee.
