Studies on quinazolines. 6. Asymmetric synthesis of (S)-(+)- and (R)-(−)-3-[[4-(2-methoxyphenyl)piperazin-1-yl]methyl]-5-methylthio-2,3-dihydroimidazo[1,2-c]quinazolines
The titled compounds have been synthesized in five steps from commercially available (R)-(+) and (S)-(−)-glycidol. The overall yield was about 29% with ee>98.5.
