1.3- Dibromopropyl methyl ether

When acrolein is allowed to react with HBr at —15° in the presence of methanol, the bromine adds primarily at the 3-position although the end-product is 1,3-dibromopropyl methyl ether the latter affords 3-bromopropanal dimethyl acetal when kept in methanol for 12 hours.206... 

Allylation of the 7-hydroxyquinoline derivative 242 with allyl bromide gave the corresponding 7-allyl ether 243 which underwent Claisen rearrangement to give the 8-allyl derivative 244. Acylation and subsequent bromination afforded the dibromopropyl derivative 245. Treatment of 245 with KOH/EtOH gave 8-hydroxypyrroloquinoline 246 that was methylated with methyl iodide to afford 247 (91JOC980) (Scheme 44).
