Polyfunctional indoles bearing substituents at C5 and C6 are prevalent in natural products, pharmaceuticals, agrochemicals, and materials. Owing to the remoteness of the C5 and C6 positions, indoles of this family can be difficult to prepare, and often require multistep syntheses. Herein, we describe a concise process that converts simple derivatives of tyrosine into 5,6-difunctionalized indoles by direct oxidation of C?H, N?H, and O?H bonds. Our work draws inspiration from the biosynthetic polymerization of tyrosine to make melanin pigments, but makes an important departure to provide well-defined indole heterocycles.

The present invention provides a compound of formula (I): wherein: ? R1 is a group selected from -CH2OH,-NH(CO)H and ? R2 is a hydrogen atom; or ? R1together with R2 form the group -NH-C(O)-CH=CH-, wherein the nitrogen atom is bound to the carbon atom in the phenyl ring holding R1and the carbon atom is bound to the carbon atom in the phenyl ring holding R2 ? R3a and R3bare independently selected from the group consisting of hydrogen atoms and C1-4alkyl groups, ? n represents an integer from 1 to 3; ? Ad represents 1-adamantyl or 2-adamantyl group, or a pharmaceutically-acceptable salt or solvate or stereoisomer thereof.
