Popis: | Schollkopf's auxiliary 16 was added to bis-lactim iodide 21 to give 1,2-bis[(3S,6R)-3,6-dihydro-2,5-dimethoxy-3-isopropylpyrazin-6-yl]ethane22 in 50% d.e. Dimer 22 was separated from its diastereoisomer 23 and deprotected using 6M HCl to afford homochiral (2R,5R)-2,5-diaminohexan-1,6-dioic acid 24. |
