By the combination of DABCO and aceticacid under solvent-free conditions, the Morita-Baylis-Hillman reaction rate of both activated and non-activated aldehydes increased significantly. The disclosed procedure is operationally simple and is compatible with a wide array of both nucleophilic and electrophilic reaction partners.

The hydroxy group of the Baylis-Hillman adducts is protected with the t-butyldimethylsilyl (TBDMS) group using the reaction of adducts 1a–h with tert-butyldimethylsilyl chloride (TBDMSCl) in the presence of lithium sulfide under nearly acidic reaction conditions.

In this work we report our results concerning the study on the in vitro antiproliferative activity of 18 Baylis-Hillman adducts and some derivatives against a panel of humor tumor cell lines. A brief qualitative structure-activity relationship study indicated that carbon-carbon double bond and the presence of an electron-withdrawing substituent at the aromatic ring are essential for the activity. A quinoline-phthalide derivative has exhibited a potent effect on the proliferation of all cell lines. It is interesting to note their special cytotoxic activity against NCIADR cell line.
