Acetic anhydride pyridine → Undec-4-ene

Participants

Reaction Steps

Subsequently, compound (10a) is acetylated with acetic anhydride-pyridine etc., thereby giving compound (11), followed by treatment with 1,8-diazabicyclo 5.4.0.!-7-undecene (DBU) in a solvent e.g. pyridine, whereby compounds (12) and (12') are formed. Compounds (12) and (12') are then hydrolyzed with a base such as sodium hydroxide, sodium methoxide, sodium ethoxide, sodium t-butoxide, etc., whereby compound (1) can be obtained.
