  A straightforward synthesis of the CERT inhibitor (1′R,3′S)-HPA-12

  摘要：

  A straightforward synthesis of the CERT inhibitor HPA-12, (1'R,3'S)-N-(3-hydroxy-1-hydroxymethyl-3-phenylpropyl)dodecanamide, is reported. The method requires only five synthetic steps from commercially available D-aspartic acid and leads to enantiopure HPA-12 in good overall yields. (C) 2015 Elsevier Ltd. All rights reserved.

  摘要：

  GRAPHICSCatalytic, enantioselective Mannich-type reactions of N-acylimino esters for direct formation of N-acylated amino acid derivatives are described. A chiral copper catalyst prepared from Cu(OTf)(2) and a chiral diamine ligand is used. A novel inhibitor of ceramide trafficking, HPA-12, is efficiently synthesized using this reaction.

  Synthesis of β-sulfinamido ketones was accomplished by the addition of silyl enol ethers derived from arylmethyl ketones to chiral sulfinimines in excellent yield and selectivity. Application of the formed β-amino substituted ketones is exemplified in the total synthesis of sphingolipid HPA-12 and the sedamine alkaloids.

  the synthesis of biologically important compounds were prepared using this novel catalytic asymmetric Mannich-type reaction, and at the same time, absolute and relative stereochemical assignments were made. In addition, it has been revealed that alkyl vinyl ethers reacted with N-acylimino esters in the presence of a catalytic amount of the Cu(II) catalyst to give the corresponding Mannich-type adducts

  日期：2003.8.1

  New ceramide trafficking inhibitors, (1R,3R)-N-(3-hydroxy-1-hydroxymethyl-3-phenylpropyl)dodecanamide (HPA-12) and a series of its analogues, were synthesized in diastereomerically and enantiomerically pure forms, and the structure-activity relationship was investigated. These analogues were stereoselectively synthesized via catalytic enantioselective Mannich-type reactions using a Cu(II)-chiral diamine 4 complex. Analysis of HPA-12 analogues having various lengths of the amide side chain showed that the optimal chain length for the inhibition of sphingomyelin biosynthesis is 13 with an IC50 of similar to50 nM. Masking of the hydroxy group at the 2'- or 3-position of HPA-12 was carried out by methylation, and it was revealed that these hydroxy groups were essential for the activity. Installation of another hydroxy group onto HPA-12 at the same position as that in the natural ceramide was also conducted, but no enhancement of the activity was observed.
