Novel achiral phenylacetylene having a bulky t-butyl group was synthesized and polymerized by a chiral catalytic system containing [Rh(nbd)Cl]2 (nbd: norbornadiene) and chiral amines to yield a one-handed helical polymer having a much higher g value than polymers with no bulky groups. Highly efficient helix-sense-selective polymerization has been achieved using a bulky monomer and a less bulky chiral cocatalyst.

, p. 365 - 367 (2007/10/03)
The base-promoted reaction of ammonium ylide 1a, which forms a cyclic hemiacetal structure, is shown to afford the anti-hemiacetal 3a in high diastereopurity, via the Stevens rearrangement followed by efficient thermodynamic epimerization.
