Bromination with N-Bromosuccinimide : Part II - An Unusual Dibromination of β-Lapachone to 3',4'-Dibromo-β-lapachone

β-Lapachone (I), on bromination with N-bromosuccinimide, affords 3-bromo-dehydro-α-lapachone (II), dehydro-α-lapachone (III), 3'-bromo-dehydro-β-lapachone (IV) and 3'-bromo-4'-hydroxy-β-lapachone (VI).The formation of II, IV and VI via an intermediate product 3',4'-dibromo-β-lapachone (IX) has been established.IX is also easily converted to 3'-bromo-4'-methoxy-β-lapachone (XIV) and 3'-bromo-4'-ethoxy-β-lapachone (XV) by treatment with methanol and ethanol, respectively.
