Bioorganic studies on plant movement, from natural products to its receptor

“…Wittig reaction of 14 followed by acidic exposure gave (–)‐methyl 12‐hydroxyjasmonate ( 16 ). Under Königs–Knorr conditions, glycosilation of 16 and Fmoc‐protected 6′‐aminogalactosyl bromide ( 17 )11 proceeded to give 18 in 37% yield, along with acetylated aglycon in 27% yield. Careful addition of AgOTf to maintain the reaction temperature low improved the yield of glycosilation 8b.…”
