To establish the correlation between the optical rotation and the absolute structure of urea inclusioncompounds (UICs), three pairs of enantiomorphic UICs were studied. This successful experimental elucidation of the handedness of UICs not only settled a question that has lasted half a century, but also showcased the feasibility of absolute structure determination by single crystal X-ray diffraction

Synthesis of omega-hydroxy carboxylic acids and alpha,omega-dimethyl diketones was successfully achieved by using alpha,omega-diols as alkylating agents under the influence of an iridium catalyst. For example, the alkylation of butyl cyanoacetate with 1,13-tridecanediol in the presence of [IrCl(cod)](2) or [IrCl(coe)(2)](2) gave rise to butyl 2-cyano-15-hydroxypentadecanoate in good yield which is easily converted to cyclopentadecanolide (CPDL). In addition, the alkylation of acetone with 1,10-decanediol in the presence of [IrCl(cod)](2) and KOH resulted in an important muscone precursor, 2,15-hexadecanedione (HDDO), in good yield.
