该中间体在本合成路线中的序号:(X)Condensation of acetaldehyde with methyl acrylate (VIII) under Bayliss-Hillmann conditions gave rise to the allylic alcohol (IX). Bromination of (IX) using N-bromosuccinimide and dimethyl sulfide proceeded with rearrangement to the allyl bromide (X). This was then coupled with aldehyde (VII) in the presence of metallic tin and catalytic amounts of HOAc to produce, after acid-catalyzed cyclization, the target methylene butyrolactone derivative.
