Description générale

3-Pyrroline is a heterocyclic building block. The excited state dynamics of 3-pyrroline by Hamiltonian model based on the vibronic coupling model has been investigated. Trifluoromethylated azomethine ylide is reported as precursor for the synthesis of 3-pyrroline building blocks. 3-Pyrrolines are reported as highly useful intermediates for the synthesis of functionalized pyrrolines, pyrrolidines and other natural products. Preparation of 3-pyrroline(2,5-dihydro-1H-pyrrole) from (Z)-1,4-dichloro-2-butene, via Delépine Reaction has been reported. It is formed as intermediate in the synthesis of N-(tert-butyloxycarbonyl)-3-pyrroline. Reaction of Me3Al and Me3Ga with 3-pyrroline is reported.
Various 3-pyrrolines (2,5-dihydropyrroles) have been synthesized by two-step reaction sequence of alkylation/alkylidene carbene CH-insertion reaction. Synthesis of 3-pyrroline has been reported by employing cis-1,4-dichloro-2-butene as starting reagent.

Application

3-Pyrroline is suitable for use in a study to investigate the core-level binding energies of simple unsaturated organic molecules bonded to the Si(001) surface by X-ray photoelectron spectroscopy (XPS). It may be used in the synthesis of renin inhibitors and vasodilators.

[reaction: see text] The gold(III) chloride-catalyzed cycloisomerization of various alpha-aminoallenes gave the corresponding 3-pyrrolines in good to high chemical yields. An interesting dependence of the chirality transfer and reactivity on the N-protecting group was observed. The 3-pyrrolines are highly useful
