- Abstract
As already extensively discussed in Part I of this series, the 'climax' of the studies at the ETH on the synthesis of corrins was reached with the conception and experimental realization of the corrin synthesis via a final ring closure between rings A and D by the photochemical A/ D-secocorrin→corrin cycloisomerization. As it was the case for the ' old corrin synthesis', described in Part IV of this series [4], the ' new synthesis' was first explored in a model system, before it became the antetype of the photochemical variant of the synthesis of vitamin B12.
