Abstract: Abstract The regio- and stereospecific synthesis of dl -4,5-dibromo-4,5-dideoxy-3,6-O-methyl-chiro-inositol is reported. Bromination of p-benzoquinone followed by reduction of the carbonyl groups with NaBH4 gave the corresponding trans-dibromodiol compound, which was reacted with sodium methoxide to… read more here.

Abstract: Treatment of Δ1-dipyrrolines with NBS afforded α,α′-dibromo-Δ1-bipyrrolines and α,α,α′,α′-tetrabromo-Δ1-bipyrrolines respectively with excellent selectivity depending on the amount of NBS. All these multibromo-substituted Δ1-bipyrrolines could be efficiently transformed into their corresponding 2,6-diazasemibullvalene derivatives via reduction with… read more here.
