摘要:Abstract(#br)Chirality transfer has been investigated with an m-phthalic diamide-linked zinc bisporphyrinate as host and chiral monoalcohols with different alkyl substituents as guests. The substituent of the guest alcohol had a significant effect on chirality transfer. An increa...

摘要:Abstract(#br)Selective synthesis of optically active rotaxane amine N -oxides was achieved with high diastereoselectivity via the effective through-space chirality transfer. Oxidation of tert -amine moiety on axle component of rotaxane with an optically active wheel component ...

摘要:Abstract(#br)Chirality transfer from an α-silylalcohol to α-carbmoyloxy- and α-siloxyallyl-carbanions was investigated using a Brook rearrangement-mediated S E 2′ protonation in γ-carbamoyloxy- and γ-siloxy-α-silylallyl alcohols. We proposed a hypothesis that the reactio...

摘要:Abstract(#br)The chirality transfer control from a single molecule to the surface molecular superstructures and to the substrate is a challenging and important aspect of two-dimensional chiral nanostructures for tailoring the functionality of molecular––metal interfaces. How...

摘要:... This is the first example of a general 1,4‐chirality transfer from sulfur to a carbon stereocenter through a sulfonium [3,3]‐sigmatropic rearrangement. This reaction delivers α‐arylated thioesters and amides under mild conditions in an atom‐economical manner. The pr...

摘要:Abstract(#br)Gold(I)‐catalysed direct allylic etherifications have been successfully carried out with chirality transfer to yield enantioenriched, γ‐substituted secondary allylic ethers. Our investigations include a full substrate‐scope screen to ascertain substituent e...

摘要:The overview of chiral levels and the chirality transfer between them. The phenomena associated with the chirality transfer found and/or theoretically predicted for achiral polar smectics are discussed. The chiroclinic effect is presented as an example in more details.

摘要:... The strategy takes advantage of [1,3]-chirality transfer from a chiral primary alcohol equivalent through an allyl cyanate-to-isocyanate rearrangement. This approach was employed in an efficient eight-step synthesis of the marine natural product, (+)-geranyllinaloisocyanide, ...
