Abstract
Irradiation of (2R,4R)-(?)- and (2S,4S)-(+)-2,4-pentanediyl-bis-2-naphthoates (1R and 1S, respectively) in organic solutions exclusively results in cubane-like antiHH photodimers in 100% yield. Asymmetric induction with 100% diastereometric excess (de) has been achieved and the absolute configuration of the yielded diastereomers has been established. Moreover, irradiation of (2R,4S)-2,4-pentanediyl-bis-2-naphthoate (1M) gives cubane-like synHH photodimers in 100% yield.
