two-step sequence from 4,4-dimethoxybutyronitrile and the respective esters by Claisen condensation and subsequent Paal–Knorr pyrrole synthesis. The sequence could be performed as a one-pot procedure delivering the pyrroles in yields of 47–72% over two steps (13 examples). Intramolecular variants of the method were applied to the total synthesis of danaidal and suffrutine A from the respective trityl-protected
rboxamides were prepared starting from enamines and Weinreb α-aminoamides. Their reaction with oganometallic compounds and subsequent cyclization constitute a versatile alternative in the Knorrpyrrolesynthesis.
its cyclization directed to the formation of N-confused chlorins. To achieve the site-directed selectivity of the cyclization, the 2-position of rac-2 was activated by an electron-withdrawing cyano function and its 1-position was blocked by a methyl group. In spite of this provision, the cyclization occurred at the apparently blocked 1-position with loss or migration of the methyl substituent.
