2,2-Dialkyl-3,4-dimethyl-5-phenyloxazolidines and 2-alkyl-2-aryl-3,4-dimethyl-5-phenyloxazolidines are formed with high diastereoselectivity from ketones and pseudoephedrine or ephedrine in the presence of scandium triflate and 4 A molecular sieves.

Iodoetherifications of all isomers of the 3-methylalk-4-en-2-ols [14∼17] proceed with excellent levels of stereoselectivity, leading to tetrasubstituted tetrahydrofurans [18∼22], via overall anti-addition to the alkene function.
