Contracted porphyrins and calixpyrroles: synthetic challenges and ring-contraction effects

“…Tackling the total synthesis of natural products has led to the development of new synthetic methods. [109][110][111][112] Similarly, resolving the various challenges in the synthesis of non-natural contracted porphyrins and calixpyrroles has contributed to the discovery of not only new reactions but also functional chromophores, metal complexes, and supramolecules. Controlling the ring strain during macrocyclization is crucial to obtain contracted porphyrinoids with a macrocyclic ring size smaller than the marginal size of compounds obtained via Rothemund-Lindsey protocol.…”

Recent advances in the synthesis of insect pheromones: an overview from 2013 to 2022

“…Due to the potential applications in pest management, insect pheromones have become attractive targets for synthetic process development throughout the decades, and so the field of pheromone synthesis also reflects the advancement of organic synthesis. 2 The synthesis of pheromones has been reviewed repeatedly by the late Professor Kenji Mori, covering the periods from 1960–1979, 3 1979–1989, 4 and 1990–2003. 5 Our group discussed some highlights of insect pheromone synthesis in the periods 2002–2004 (ref.…”
