Abstract

A new type of sulfur contained C 2 symmetric chiral substance

5 bis [2 (4 ethyl)oxazoliyl]thiophene(BEOZT)

was synthesized in 39% total yield from 2

5 thiophene dicarboxylic acid

which went through the reacting with (-) 2 amino 1 butanol

amidation

halogenation and dehydrating cyclization

In our application study of chiral reagents

BEOZT had showed to be an excellent NMR shift reagent in distinguishing (R) and (S) 1

1’ bi 2 naphthol. Its application in asymmetric synthesis is in further study.
