Synthesis of the hindered N,N,N′-trisubstituted guanidine moiety of martinelline and martinellic acid
Snider, Barry B.,O'Hare, Sean M.
, p. 2455 - 2458 (2001)
Hindered guanidines can be prepared by reaction of cyanamides with amines in hexafluoroisopropanol at 90-120°C. This sequence was used for preparing guanidinium acid 21 as a model for martinellic acid.
