A one-two punch: two potentially biosynthetically relevant cyclizations of a keramadine analogue give agelastatin A. A diastereoselective C-ring formation, which proceeds through a 5-exo-trig cyclization or a Nazarov cyclization of a red-colored N-acyliminium intermediate, generates the three contiguous stereocenters of the cyclopentane core. A silica gel assisted cyclization of a nagelamide J analogue gives agelastatin A. ...[more]
