• . All solvents and chemicals used in the syntheses were of reagent grade and were used without further purification. Aldehydes 1 [16][30], 2 [17], 3 [18] and organocatalysts 14 [31], 15 [32], 16 [33] were prepared by known procedures. Silyl ethers of diarylprolinols 17 and 18 were obtained from Sigma
