Highly Stereoselective Intramolecular Diels–Alder Reaction of Decatrienoates Activated by<i>t</i>-Butoxycarbonyl, Chloro, and Sulfonyl Groups at the Terminal Position
HighlystereoselectiveintramolecularDiels–Alder (IMDA) reaction of decatrienoates has been achieved by using a more sterically hindered ester group, i.e., t-butoxycarbonyl, or electron-withdrawin...
