Carbon-carbon bond formation is one of the most fundamental reactions in organic
chemistry. The development of efficient and selective methods for the construction of carbon …

In a patent application published in 1972, Baylis and Hillman reported the reaction of
acetaldehyde with ethyl acrylate and acrylonitrile in the presence of catalytic amounts of 1, 4 …

The acrylate ester of salicylaldehyde, in the presence of DABCO, affords a crystalline
coumarin salt. Formation of this derivative confirms a vital intermediate in the mechanism of …

This review focuses on applications of the Baylis-Hillman reaction in the synthesis of various
heterocyclic products, which include indolizines, chromenes, thiochromenes, coumarins and …

Evidence is presented which supports the intermediacy of dipolar Baylis–Hillman-type
adducts in the synthesis of coumarin and chromene derivatives from the reaction of 2 …

Abstract Treatment of salicylaldehydes with acrylate derivatives in the presence of 1, 4-
diazabicyclo [2.2. 2] octane (DABCO) has been shown to afford both coumarin and …
