Stereoselective Synthesis of (<i>E</i>)-β-Aryloxyl and Alkyloxyl Acrylates Through DABCO-Catalysed Michael Additions of Phenols and Alcohols to Ethyl 2,3-Butadienoate
The development of DABCO-catalysed Michaeladdition of phenols and alcohols to ethyl 2,3-butadienoate provides an efficient synthetic pathway to (E)-β-aryloxyl and alkyloxyl acrylates in i-PrOH or under solvent-free conditions. The major advantages of the present method are wide substrate scope, mild reaction conditions, high stereoselectivity, and good reaction yields.

The first example of efficientasymmetrichydrogenation of challenging β‐aryloxyacrylic acids was realized using a RhI‐complex based on the heterocombination of a readilyavailable chiral monodentate secondary phosphine oxide (SPO) and an achiral monodentate phosphine ligand as the catalyst. Excellent enantioselectivities (92–>99 % ee) were achieved for a wide variety of chiral β‐aryloxypropionic acids
