Knoevenagel, with allylic esters

A useful extension of sulfoxide-sulfenate rearrangements exploits the greater stability of allylic vs. vinylic sulfoxides.For example, the Knoevenagel product (202) is deconjugated under the conditions of its formation. This sets the stage for a 2,3-rearrangement in the same pot (equation 66). Optically active condensation products give hydroxy esters (201) with 64-72% 50-80% ee were reported for... [Pg.902]
