  4. Measured on Varian HR-60 or AR-60 spectrometers in CDCl3 solution using tetramethylsilane as internal standard. All signals are reported in p.p.m. as δ units (seeC. Djerassi, T. Nakano, A. N. James, L. H. Zalkow, E. J. Eisenbraun, andJ. N. Shoolery, J. org. Chem.26, 1192 (1961)). We are indebted to Dr.J. N. Shoolery (Varian Associates) and Dr.L. J. Durham (Stanford University) for these measurements.
