Gold‐ringing! Modification of the substitution at C2 drives an entirely different cyclization of N‐tethered allenylindoles. An efficient cycloisomerization takes place for the case of R being hydrogen, that is, compatible with additional functional groups. A methyl at C2 precludes this possibility and launches a stepwise process that can be tuned to yield macrocyclic trimers.

Reported is on the photo Co metal hydride hydrogen atom transfer (MHAT) reaction for chemoselective allene functionalization by using Co-porphines as catalysts and the Hantzsch ester as an H atom and electron donor. The merger of Co MHAT and Ti catalysis under photoredox conditions enabled successful carbonyl allylation, providing access to valuable β-functionalized homoallylic alcohols with exceptional

Platinum-Catalysed Bisindolylation of Allenes: A Complementary Alternative to Gold Catalysis

Pt versus Au: Platinum‐catalysed addition of nucleophiles to allenes follows a distinctly different pathway to the process catalysed by gold(I) complexes; the platinum catalyst leads to different products with indoles involving a bisindolylation reaction, whereas gold(I) gives allyl indoles from a single addition (see scheme).
Pt vs Au:铂催化的亲核试剂向丙二烯的加成遵循截然不同的金(I)络合物催化的过程。铂催化剂可生成涉及双吲哚基化反应的吲哚的不同产物,而金(I)只需一次添加即可生成烯丙基吲哚(参见方案)。
