Artykuł
Metallo-tetrahydrobiline rac-8 was prepared to investigate 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.
