Temperature conversion among scales

Note See Appendix A for conversion among the temperature scales mentioned. = 1958 helium vapor pressure temperature scale. [Pg.523]

The key structural features of compound 1 are the chiral cis-diaryl benzox-athiin fused ring system, two phenols, and one phenol ether linkage with the pyrrolidinylethanol. Originally, SERM 1 was prepared by medicinal chemists from a key ketone intermediate 5 shown in Scheme 5.1. Compound 5 was prepared in four steps with rather low yield [4a], Among these steps, the high temperature de-methylation step and the use of extremely toxic MOM-C1 were not particularly suitable for scale-up. The ketone 5 was then brominated with PhMe3NBr3 (PTAB) and coupled with thiophenol 7 to produce adduct 8. The key step of the synthesis was the conversion of adduct 8 to cis-diaryl benzoxathiin 9 under the Kursanov-Parne reaction conditions (TFA/Et3SiH). This novel reaction allowed the formation... [Pg.144]

We can convert among the temperature scales by adjusting the zero point and the size of the unit. Useful equations for conversions are ... [Pg.163]
