C-H functionalization of benzyl silyl ethers by means of rhodium-catalyzed insertions of aryldiazoacetates can be achieved in a highly diastereoselective and enantioselective manner by judicious choice of chiral catalyst or auxiliary. The use of (S)-lactate as a chiral auxiliary resulted in C-H functionalization with moderate diastereoselectivity and enantioselectivity. The best results were achieved using Hashimoto's Rh2((S)-PTTL)4 catalyst.

A catalytic, direct asymmetric cross-aldol reaction of two different aldehydes in the presence of water is catalyzed by a novel combined proline-surfactant organocatalyst. Neither an organic cosolvent nor additional acid is necessary.

Ketones, dienes, and B2(pin)2 undergo a stereoselective multicomponent coupling reaction in the presence of catalytic amounts of Ni(cod)2 and P(t-Bu)3. A subsequent oxidation furnishes 1,3-diols as the major reaction product.

Cu-catalyzed highly regio- and stereoselective 1,4-protoboration of dienylboronates provides unsymmetrical 1,4-bifunctional allylboron reagents. A subsequent chemoselective allylboration with aldehydes followed by oxidative workup give diol products with high diastereoselectivity.

A copper(I)-catalyzed asymmetric borylative propargylation of simple ketones offers broad substrate scope, good tolerance of functional groups, high diastereo- and enantioselectivities, and reaction robustness. The borylative product can also serve as a cross-coupling partner in Pd-catalyzed Suzuki-Miyaura reactions.

A novel microwave-assisted, operationally simple, tandem bis-aldol reaction of ketone with paraformaldehyde catalyzed by polystyrenesulfonic acid in aqueous medium delivers 1,3-dioxanes in high yield.

An organocatalytic β-hydroxylation of α,β-unsaturated aldehydes with commercially available (E)-benzaldehyde oxime gives the corresponding chiral carbonyl β-oxime ethers in high yields and with excellent enantioselectivities. The chiral carbonyl β-oxime ethers can be reduced to the corresponding 1,3-diols in high yields.
