  Thiazole-Based Stereoselective Routes to Leucine and Phenylalanine Hydroxyethylene Dipeptide Isostere Inhibitors of Renin and HIV-1 Aspartic Protease

  摘要：

  A new synthesis of hydroxyethylene dipeptide isosteres for Leu-Leu and Phe-Phe in their gamma-lactone form 1a and 1b employing beta-amino-alpha-hydroxy aldehydes with singly and doubly protected nitrogen has been developed. These key intermediates, which are available through the thiazole-aldehyde synthesis from L-leucine and L-phenylalanine, were converted to alkanoates by Wittig olefination and reduction of the ethylenic double bond. Lactonization and stereoselective alkylation at C-2 of the resulting lactones completed the building up of the structural framework. Overall yields were in the range 16-19% for 1a and 22-23% for 1b.
