Summary Three useful developments in the preparation of guanidines are presented herein. A collection of bis(Boc)aminoalkylguanidines (n=2, 3, 4 and 6; Boc=tert-butoxycarbonyl), known to be prone to cyclisation, have been synthesised and isolated without chromatography as shelf-stable sulfonate salts in good yield (up to 94%). Secondly, a selection of guanidines tethered to a range of other functional groups, including alkyne, alkene, alcohol, and azide, have been prepared in good yields with no requirement for a purification step, and thirdly an inexpensive, high-yielding (93%), and facile synthesis of N,N'-bis(Boc)guanidine, a key precursor for N,N'-bis(Boc)-N'-triflylguanidine, is described in which the need for chromatographic purification is again obviated.
