Fig. 3: (Aza)indole substrate compatibility table.

From: Unveiled reactivity of masked diformylmethane with enamines forming resonance-assisted hydrogen bonding leads to di-meta-substituted pyridines

Fig. 3

(Aza)indole substrate scope was explored using ethynyl phosphinate (2e) and 2-ethynyl pyrimidine (2i) as model acetylene substrates. Blue coloured structures show the compartments constructing newly generated pyridine core. Red coloured structures show the meta-substituent originated from acetylene.
