The Baylis-Hillman reaction was greatly accelerated by use of octanol as an additive. Under the octanol-accelerated Baylis-Hillman conditions, unactivated aldehydes such as aliphatic aldehydes and aromatic aldehydes with electron-withdrawing substituents were readily converted into the desired products in good to high yields.

The hydroxylation of Baylis-Hillmanadducts 1 is shown to proceed with high levels of diastereocontrol. A mechanistic rationale to explain this selectivity is discussed.

The SYN diastereospecific epoxidation of acyclic beta-hydroxyketones (beta-hydroxyacrylates) and cyclic beta-hydroxyketones using titanium and vanadium catalysts is reported. Some initial results on the asymmetric epoxidation of these systems using the Sharpless titanium-tartrate catalyst are also described.
