Ultrasound-assisted synthesis of substituted guanidines from thioureas

© 2016 Elsevier Ltd. Ultrasound-assisted synthesis of guanidine derivatives was developed using 2,4,6-trichloro-1,3,5-triazine as an inexpensive dehydrosulfurization reagent. Both 1,3-alkylaryl- and 1,3-diaryl-thioureas were rapidly converted into carbodiimides before subsequent reaction with aromat...

Both 1,3-alkylaryl- and 1,3-diaryl-thioureas were rapidly converted into carbodiimides before subsequent reaction with aromatic or aliphatic amines. The method allows rapid access to highly substituted guanidines in good to excellent yields under mild conditions and with minimal use of solvent. 2017-09-28T04:25:32Z 2017-09-28T04:25:32Z 2016-01-15 Journal 00404039 2-s2.0-84958580862 10.1016/j.tetlet.2016.02.050 https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=84958580862&origin=inward http://cmuir.cmu.ac.th/jspui/handle/6653943832/42153
