The synthesis of 2C-T-17 R required starting with the S isomer of secondary butanol. The S 2-butanol in petroleum ether gave the lithium salt with butyllithium which was treated with tosyl chloride (freshly crystallized from naphtha, hexane washed, used in toluene solution) and the solvent was removed. The addition of 2,5-dimethoxythiophenol, anhydrous potassium carbonate, and DMF produced S 2,5-dimethoxyphenyl s-butyl sulfide. The conversion to R 2,5-dimethoxy-4-(s-butyl-thio)benzaldehyde (which melted at 78-79 °C compared to 86-87 °C for the racemic counterpart) and its conversion in turn to the nitro-styrene, S -2,5-dimethoxy-4-(s)-butylthio-B-nitrostyrene which melted at 70-71 °C compared to 68-69 °C for the racemic counterpart, followed the specific recipes above. The preparation of the intermediates to 2C-T-17 S follows the above precisely, but starting with R 2-butanol instead. And it is at these nitrostyrene stages that this project stands at the moment.

Furthermore the isolation of low-molecular weight products by Viehe and coworkers, especially when bulky oc-ferr-butylthio substituents are placed on the olefin, is also perfectly compatible with classical theories. The steric hindrance of a fBuS-group was calculated to be greater than the steric hindrance of a neopentyl (CH2C(CH3)3), a cyclohexyl, or a t-butyl group [84].

The structure of 6-(tert-butylthio)-y0-CD was characterized by Tabushi et al. [21]. The compound of 6-O-(tert-butylthio)-y0-CD was prepared from the reaction of 6-O-(p-toluenesulfonyl)-y0-CD with tert-butylmercaptan and recrystallized in water. This is the first example of the determination of crystal structure of monosubstituted CD derivatives and the first evidence concerning the supramolecular polymer of an inclusion complex of a monosubstituted CD. The crystal structure of 6-O-(tert-butylthio)-y0-CD was arranged around the two-fold axis to yield a polymeric structure, in which the tert-butyl group is intermolecularly included in the cavity of CD (Fig. 3).

A mixture of 72 g POCI3 and 67 g N-methylformanilide was heated for 10 min on the steam bath. To this claret-colored solution was added 28 g of 2,5-dimethoxyphenyl (t)-butyl sulfide, and the mixture heated for 10 min on the steam bath. This was then added to 1 L of H20 and stirred overnight. The residual brown oil was separated from the water mechanically, and treated with 150 mL boiling hexane. The hexane solution was decanted from some insoluble tars, and on cooling deposited a dark oil which did not crystallize. The remaining hexane was removed under vacuum and the residue combined with the above hexane-insoluble dark oil, and all distilled at 0.2 mm/Hg. An early fraction (70-110 °C) was largely N-methyl-formanilide and was discarded. Crude 2,5-dimethoxy-4-(t-butylthio)benzaldehyde came over at 120-130 °C... 

The (n)-butyl compound, named 2C-T-19, has been taken to the nitrostyrene stage. Reaction between 2,5-dimethoxythiophenol and (n)-butylbromide with KOH gave 2,5-dimethoxyphenyl (n)-butyl sulfide as a colorless oil. This, with phosphorus oxychloride and N-methylformanilide, provided 2,5-dimethoxy-4-(n-butylthio)benzaldehyde as pale orange solids from MeOH, with a melting point of 78-79 °C. This, with nitromethane and ammonium acetate, gave 2,5-dimethoxy-4-(n-butylthio)-beta-nitrostyrene, with a melting point of 133-134 °C from either IPA or acetonitrile.
