A highly efficient palladiumcatalyzed decarboxylative allylic rearrangement of alloc indoles has been developed. This can also be combined with a Suzuki–Miyaura cross-coupling reaction in a single pot transformation. Substituted alloc groups and benzylic variants have also been demonstrated alongside promising initial results on the enantioselective variant.

the benzofuro[3,2‐b]indoline framework could be obtained by PIDA‐mediated direct oxidative coupling of 2,3‐disubstituted‐indoles with phenols. Application of this chemistry allows for an eight‐step total synthesis of phalarine from commercially available tryptamine.
我们首次报道,可通过PIDA介导的2,3-二取代吲哚与酚的直接氧化偶合获得苯并呋喃[3,2- b ]二氢吲哚骨架。该化学方法的应用使得可以从市售的色胺中进行八步法合成全草胺。
Aryl Hydrazide beyond as Surrogate of Aryl Hydrazine in the Fischer Indolization: The Synthesis of <i>N</i>-Cbz-indoles, <i>N</i>-Cbz-carbazoles, and <i>N</i>,<i>N′</i>-Bis-Cbz-pyrrolo[2,3-<i>f</i>]indoles

Aryl hydrazides underwent the Fischer indolization reactions, while the N-carbamate group(s) remained intact to directly provide N-Cbz-indoles. This new method allowed the synthesis of various N-Cbz-carbazoles and N,N'-bis-Cbz-pyrrolo[2,3-f]indoles.
