Synthetic Studies Relevant to Biosynthetic Research on Vitamin B12. Part 2. Syntheses of C-Methylated Chlorins Via Lactams

C-Metylyted chlorins have been synthesised by two approaches.For one, ring-B and ring-C of the final chlorin were built sequentially onto a thiolactam system which acted as the A-D component.The preferred alternative method involved joining together a lac
