Zirconium-catalyzed enantiotopic group-selective synthesis of hydrindanes
摘要:
When a THF solution of 12b and (S)-(EBTHI)ZrBINOL (10 mol%) was refluxed in the presence of BuMgCl (4 equiv.) for 4 h, zirconium-catalyzed enantiotopic group-selective cyclization proceeded and hydrindane 13b with 87% ee was obtained in 35% yield. (C) 2003 Published by Elsevier Science Ltd.
