| Abstract: | An efficient synthesis of tert-butyl-(2S)-2-(tert-butoxycarbonyl)amino]-4-(2-oxiranyl) butanoate (5), the key intermediate for preparation of collagen cross-links (+)-pyridinoline (Pyd, 1) and (+)-deoxypyridinoline (Dpd, 2) was described from (4S)-5-(tert-butoxy)-4-(tert-butoxycarbonyl)amino]-5-oxopentanoic acid (6) in six steps. Also, an improved synthesis of iodide (2S)-(−)-4b was presented. |
