Abstract

Raney nickel reductions of nickel(II) anhydromesorhodoporphyrin XV (17) provide a series of readily separable nickel(II) hydroporphyrins. Apart from the two expected isobacteriochlorins 19 and 22, two hexahydroporphyrins 20 and 21 were obtained as the major reduction product (32%). Hexahydroporphyrins of the pyrrocorphin type (7) observed in Raney nickel reductions of pheophorbides were not observed. The most novel hydroporphyrin isolated was an octahydroporphyrin 23 obtained in 5% yield by further reduction of the hexahydroporphyrin isomers. © 1987, American Chemical Society.
