A novel optically active bisphosphine ligand CDP containing a C2- symmetric cyclobutane ring was prepared from an enantiopure anti head-to- head coumarin dimer. CDP was successfully applied to the rhodium-catalyzed asymmetric hydrogenation of a

A new class of bisphosphine ligands (5, 6) with a cyclobutane backbone have been designed and synthesized on the basis of a privileged C2 scaffold of head-to-head coumarin dimer, among which ligand 5a was found to show excellent activity and en

Photochemical dimerization of methyl methoxycinnamates was studied. Dimer formation was observed both in unsensitized and in sensitized reactions. The reactions showed a high stereoselectivity.

, p. 1895 - 1902 (2007/10/02)
The chiroptical property of optically active polyamides (3a - i), derived from (-)-anti head-to-head coumarin dimer (1), was investigated by comparing their UV and circular dichroism (CD) spectra with those of the corresponding model diamides (8a - i) in
