both allylic and propargylic groups were well tolerated under our reaction conditions. Alkyl substituted aniline (4j) suffered from suppressed reactivity and observed poorer yield (∼6% by1H NMR). We presume this lower reactivity of aniline to be a consequence of decreased arene electron density: ...
The 1H NMR spectra of t-BuSH and t-Bu2S2 under CO2 (Fig. 4a,b, and Supplementary Fig. 14) showed singlets at 1.38 and 1.29 ppm, respectively. On the other hand, we found that the new signals emerged at 0.88, 0.89, and 1.19 ppm in the 1H NMR spectrum of a THF-d8 solution...
2H NMR measurements of orientational order and spectral densities in the nematic, smectic A and smectic B phases of p-hexyloxybenzylidene-p -fluoroaniline (FAB-OC6) deuterated in the benzylidene methine group and in the aniline ring are reported. The orientational order parameters obtained indicate ...

Unique H-NMR spectral patterns can be obtained from biaxially ordered smectic E and G phases, where only one director of the phase is aligned by the magnetic field. Two effects on the shape of the deuterium spectral pattern are demonstrated: (1) The effect of a motionally induced asymmetry ...
Next, we investigated the possibility of using a reduced indole substrate, namely dihydromitragynine58. With this compound, we observed a partial conversion of starting material to the corresponding 11-boronate ester (50% conversion as determined by 1H NMR). However, the following halogenation ...
