Enhancement of endo selectivity in Diels–Alder reactions of methyl (E)-3-nitroacrylate with (E)-1-oxybuta-1,3-dienes

Abstract

(E)-1-Acetoxybuta-1,3-dienes show enhanced endo selectivity in Diels–Alder reactions with methyl (E)-3-nitroacrylate compared with (E)-1-methoxybuta-1,3-dienes and (E)-1-trimethylsilyloxybuta-1,3-dienes.
