Dynamic asymmetric induction (DYASIN) of racemic dynamic chiral heterohelicenes afforded their highly enantioenriched forms (up to 96% ep) in quantitative yields. These heterohelicenes were readily converted into semi-static axial-chiral 1,1′-binaphthyl derivatives in a stereospecific manner.

A new series of 1,2-naphthoquinone derivatives was synthesized by various synthetic methods and evaluated for their ability to inhibit protein tyrosine phosphatase 1B (PTP1B). 1,2-Naphthoquinone derivatives with substituent at R(4) position showed submicromolar inhibitory activity, and compound 24 demonstrated 10- to 60-fold selectivity against the tested phosphatases. Also, several 4-aryl-1,2-naphthoquinone derivatives with substituents at R(3), R(6), R(7), or/and R(8) showed submicromolar inhibitory activity and good plasma stability.
