Participants

Reaction Steps

4,4-(Dimethyl-1,1-dioxido-1,2,5-thiadiazolidin-2-yl)-triphenyl phosphonium (1.15 g, 2.80 mmol) was added in one portion to a stirred solution of (S)-(−)-3-chloro-1-phenyl-1-propanol (317 mg, 1.86 mmol) and 7-hydroxybenzo[b]thiophene (280 mg, 1.86 mmol) in dry THF (5 mL) under an inert atmosphere on nitrogen. The resulting suspension was allowed to stir for a further 18 hrs before the solvent was removed in vacuo. The residue was triturated with hexane (ca. 15 mL) and the solid filtered, the filtrate was concentrated in vacuo and the resulting pale yellow oil was purified by flash chromatography eluting silica gel with hexane:ether [95:5] to yield the title compound as a colourless oil (240 mg, 43%); Rf=0.78 in hexane:ether [10:1]; δH (300 MHz, CDCl3) 7.66–7.00 (9H, m, Ar); 6.55 (1H, d, Ar), 5.80–5.72 (1H, m, CHO), 3.91–3.60 (2H, m, CH2), 2.62–2.50 (1H, m, CHH), 2.38–2.22 (1H, m, CHH).
