Indole-olefin-oxazoline (IndOlefOx)-ligands: synthesis and utilization in asymmetric Rh-catalyzed conjugate addition
摘要:
The synthesis and utility of novel indole-olefin-oxazoline (IndOlefOx)-ligands are described. The use of these ligands was demonstrated in rhodium catalyzed asymmetric conjugate additions between 2-cyclopentenone, 2-cyclohexenone, and 2-cycloheptenone with different boron reagents with good yields and enantioselectivities of up to 94%.
