(2S)-decane-1,2-diol

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Chiral 2-n-octyl-2,3-dihydro-thieno[3,4-b][1,4]dioxine was synthesized by transetherification of 3,4-dimethoxythiophene with (S)-1,2-decanediol and purified to a purity of 99.24% as described in INVENTION EXAMPLE 1. It was characterized by GC-MS and 1H-NMR-spectroscopy, and exhibited a specific rotation of −88° at 25° C. and 436 nm in hexane. purified to a purity of 99.24% a specific rotation of −88° at 25° C.

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.
