Hemiaminals are common in natural products as well as bioactive compounds. Hemiaminals with an indole moiety are particularly attractive due to the significant bioactivity of indoles. Herein, we reported an efficient organocatalyzed indole N-1 nucleophilic addition of α-oxoaldehydes to deliver various indole hemiaminals in good yields (up to 92%) and excellent regioselectivities with DABCO or triethylamine
