Solid support mediated chemo and regioselective synthesis of 3H-1,5-benzodiazepines from diversely substituted α-oxo ketene dithioacetals

Solvent free, dry media supported synthesis of a series of 4-aryl/heteroaryl-2-methylthio-3H-1,5-benzodiazepines by chemo- and regioselective cyclization of substituted α-oxoketene dithioacetals with o-phenylenediamines is described. The X-ray crystallogr

A new route to 3H-1,5-benzodiazepines and heterocyclic ketene animals from benzoyl substituted ketene dithioacetals and diamines

Heterocyclic ketene aminals 5 or 3H-1,5-benzodiazepines 4 were obtained from the reaction of benzoyl substituted ketene dithioacetals 1 with various diamines 2. The mechanism of formation of these two different products are discussed.
