The molecular ,formula, of Cj-NCC-2 (1) was determined with high-resolution MS as C 35 H 40 N 4 O 7, based on its pseudomolecular ion at m/z = 629.2990. This result indicated Cj-NCC-2 (1) has a molecular weight smaller than the one of any known NCC (6, 18, 20–24) and relates to Cj-NCC-1 (3) by its lack of one oxygen atom.
