Gold‐catalyzedaminoaromatizations of 1,n‐diynes with anthranils afforded 1‐amino‐2‐napthaldehyde derivatives efficiently. In this reaction sequence, anthranils preferably attack at gold‐coordinated prop‐3‐yn‐1‐ols to generate α‐imino gold carbenes that enable subsequent cyclizations with the other alkynes. Chemical functionalizations of the resulting 1‐amino‐2‐napthaldehydes are presented to manifest
syn-selective hydrochlorination upon heating with hydrochloric acid through a pseudo-intramolecular process. This reaction is initiated by formation of anilinium salt, which facilitates the efficient electrophilic addition because of the spatial proximity of the reagents. In this reaction, overaddition is not observed.

The present invention relates to compounds of formula (I) and salts, stereoisomers, tautomers or N-oxides thereof that are useful as modulators of STING (Stimulator of Interferon Genes). The present invention further relates to the compounds of formula (I) for use as a medicament and to a pharmaceutical composition comprising said compounds.
An efficient synthesis of N-acetyl-2-substituted indole derivatives via direct intramolecular hydroamination of N-acetyl-2-alkynylaniline derivatives was developed. The reaction could be applied to a wide range of substrates employing only 1–2 mol% of PtCl4 as the catalyst to furnish the desired indole products in moderate to excellent yields. The current protocol is efficient, reliable and scalable
