- Synthetic method for 2,4,6-trimethylbenzene-1,3,5-triamine and N,N,N-triacylated product
-
The invention provides a synthetic method for 2,4,6-trimethylbenzene-1,3,5-triamine and an N,N,N-triacylated product. The method comprises the following steps: S1, performing a nitration reaction on mesitylene with structural formula IV as a reaction raw material in the presence of a mixed acid of fuming nitric acid and concentrated sulfuric acid, and after the nitration reaction, performing filtration and drying to obtain 1,3,5-trimethyl-2,4,6-trinitryl benzene with structural formula III; S2, performing a hydrogenation reaction on 1,3,5-trimethyl-2,4,6-trinitryl benzene and a reducer hydrazine hydrate to reduce nitryl to amino, and performing purification to obtain 2,4,6-trimethylbenzene-1,3,5-triamine with structure formula II; and S3, performing an acylation reaction on 2,4,6-trimethylbenzene-1,3,5-triamine and an acylation reagent to obtain N,N,N-triacyl-2,4,6-trimethylbenzene-1,3,5-triamine with structural formula I.

- A new synthetic strategy to prepare throne and calix diastereoisomers of parallel tris-Trger's bases
-
The calix diastereoisomers of the parallel tris-Trger's base (tris-TB) derivatives were suggested as potential cavitands in 2002, and the first members of this cavitand family were introduced in 2007. The synthetic strategy enabling the preparation of nap
