S. Sarac et al., Analytical resolution of 4-aryl-1,2,3,4,5,6,7,8-octahydroquinazoline-2-thiones using a cellulose chiral stationary phase, ANAL LETTER, 32(6), 1999, pp. 1245-1254
Racemic 4-aryl-1,2,3,4,5,6,7, 8-octahydroquinazoline-2-thiones were resolve
d into their enantiomers by HPLC on cellulose tris(4-methylbenzoate) coated
on silica gel using ethanol:n-hexane (70:30) as a mobile phase. A convenie
nt method for preparation of cellulose tris(4-methylbenzoate) chiral statio
nary phase was described and the enantiomers were characterized by some chr
omatographic data.
