and organo ) and turbo or propeller chirality , orientational chirality ; At the macro and polymeric molecular level, it encompasses multilayer chirality (rigid helical and flexible folding ), as well as topological and inherent chirality . Among these categories, orientational chirality is the most recent addition, defined by the C(sp²)-C(sp³) or C(sp)-C(sp³) axis with remotely anchored blockers . The orientational model exhibits three major energy barriers, contrasting with the six found in classic Felkin-Ahn or Cram models. This new form of chirality was revealed through our study of multilayer chiral frameworks via asymmetric catalytic C-C bond formation (Scheme 1). Figure . Turbo Chirality in Multilayer Frameworks (x, y and w show pro chiral center, orientational axis and aromatic interaction) X-ray diffraction of the multilayer framework displays orientational and turbo chiral patterns through three propellers (Figure ), Specifically, aromatic-aromatic interactions differentiate the two phenyl groups on the P=O moiety and produce a turbo chiral pattern, with three aromatic rings surrounding the P=O axis. The bridge between the two piers is a non-symmetrical benzo[c] thiadiazole ring, which also acts as a significant asymmetric factor. When we attempted to explore new chiral architectures by replacing the benzo[c][1,2,5]thiadiazole ring with a symmetric phenyl ring, the asymmetric catalytic C-C bond formation was unsuccessful, resulting in minimal product formation under various conditions. Shifting focus, we investigated simpler two-layer frameworks attached to chiral amide auxiliaries. We discovered that two phenyl rings on the naphthyl pier could be arranged asymmetrically, leading to the identification of a new chirality pattern, which we are provisionally calling "staircase chirality". This chirality is illustrated in Figure , featuring two symmetrical layers that slip in opposite directions. Two functional groups, represented by two spheres, may be identical or different. In this report, we present our preliminary findings on this novel chirality element.
