Abstract

Efficient regioselective synthesis of β-amino alcohol derivatives, including enantioenriched ones, by a tetraarylphosphonium salt-catalyzed coupling reaction of epoxides with trichloroacetonitrile is described. Formal [3+2] cycloaddition, followed by hydrolysis, proceeded smoothly to afford N-protected β-amino alcohols in good yields. [ABSTRACT FROM AUTHOR]

7. Tuning the depth of bowl-shaped phosphine hosts: capsule and pseudo-cage architectures in host–guest complexes with C60 fullerene

Author

Yamamura, Masaki, Sukegawa, Kimiya, and Nabeshima, Tatsuya

Abstract

Bowl-shaped phosphine molecules, whose bowl geometry can be controlled by a variation of the axial substituent, were synthesized, and used as host molecules to encapsulate C60. Host molecules with relatively shallow bowls formed a chiral capsule, while hosts with deeper bowls formed an achiral pseudo-cage.
