First total synthesis of the proposed structures of β‐indoloquinazoline alkaloids orisuaveolines A and B is reported. The key steps of the synthesis included a Pictet‐Spengler reaction to build a six‐member lactam which further transformed into target molecular by a one‐pot condensation. This synthesis provided an access to the proposed structures of orisuaveolines A and B in a short and convenient
