Abstract
'Ole in one! Treatment of β-amino alcohols with CS 2 under alkaline conditions gave 1,3-thiazolidine-2-thiones, which were then treated with benzyne generated in situ. The reaction underwent an unprecedented addition-elimination process to give the desired olefins in 60-87 yields (see scheme; DBU=1,8-diazabicyclo[5.4.0]undec-7-ene).
