with molybdenum hexacarbonyl and cumyl peroxide, proceed through an indoxyl intermediate to produce significant amounts of indirubin through a competing mechanism. Modulation of this system to lower temperatures allows for careful tuning, leading to selective production of indirubins in a general process. A systematic assay of indoles show that electron deficient indoles work well when substituted at the
Enzymatic Approach for the Biosynthesis of IndigoidDyes: A stepwise laboratory evolution of P450 enzyme is developed and used to establish an environmentally benign enzymatic approach for the biosynthesis of indigoiddyes from indole derivatives with high isolation yields, improving upon existing methods.
