Description

2,3-Dibromo-N-methylmaleimide can be used to synthesizebis-indolylmaleimides via reaction with indolyl magnesium bromide.It can also undergo mono-cross coupling with triorganoindium derivatives which can be further coupled with naphthodithiophene to form an intermediate for [5]thiahelicene synthesis.
