Special Topic 6.14 Photochemical synthesis of large rings 

Facile synthesis of isooxyskytanthine (300), a monoterpene alkaloid, was performed by photoreductive intramolecular cyclization of the 5-oxocyclopentanecarboxamide 

Case Study 6.23 Organic synthesis - Diels-Alder trapping of photoenols 

The total synthesis of cytotoxic agents hamigerans was achieved via the photoenoliza-tion of substituted benzaldehydes and the subsequent Diels Alder (dark) reaction.983 Two species, E- and Z-isomers of 305, while being interconverted by E Z
