title: Solid-phase synthesis of 2,5-dihydro-1H-pyrroles, 1,3-dioxo-2,3,5,7a-tetrahydro-1H-pyrrolo[1,2-c]imidazoles and 1,4-dioxo-1,2,3,4,6,8a-hexahydropyrrolo[1,2-a]pyrazines using a supported selenium resin.
abstract: A versatile combinatorial approach was developed for the rapid synthesis of 2,5-dihydro-1H-pyrroles, 1,3-dioxo-2,3,5,7a-tetrahydro-1H-pyrrolo[1,2-c]imidazoles, and 1,4-dioxo-1,2,3,4,6,8a-hexahydropyrrolo[1,2-a]pyrazines libraries. The synthetic strategy includes electrophilic addition, dehydrohalogenation, 1,3-dipolar cycloaddition, N-acylation, amino carbonylation-cyclization, N-alkylation, lactamization, and oxidation-elimination.
