Convenient synthesis of mono- and ditosylated 1,4,7-triazacyclononane
Lazar,Takacs
, p. 3141 - 3144 (2001)
Mono- and ditosylated 1,4,7-triazacyclononane (2, 3) were synthesized by rapid partial deprotection of 1,4,7-tritosyl-1,4,7-triazacyclononane (1) in vigorously stirred refluxing acetic acid-hydrobromic acid mixture.
