Abstract

trans-2-Phenylcyclohexanol has been employed as a chiral auxiliary in the inter [4 + 2]/intra [3 + 2] tandem cycloaddition of nitroalkenes with chiral vinyl ethers. A novel reversal of selectivity between cycloadditions catalyzed by the Lewis acids Ti(O-i-Pr)2Cl2 and MAPh has been discovered.
