Triphenylphosphine Catalyzed Stereoselective Synthesis of O‐Vinylcyclopentenones.

Abstract

Triphenylphosphine Catalyzed Stereoselective Synthesis of O-Vinylcyclopentenones. -The procedure described represents a simple entry into the synthesis of O-vinylcyclopentenones (III) thought as potentially synthetic intermediates. -(BAHARFAR*, R.; OSTADZADEH, A.; ABBASI, A.; J.

Recyclable gold(iii) dipyridine complex immobilized on Fe3O4magnetic nanoparticles: synthesis of 2,6-dihydro[2,1-a]isoindole under mild conditions

“…The recent work of Robabeh Baharfar,9 showed that the Zwitterionic intermediates formed between alkyl isocyanides (1) and dialkyl acetylenedicarboxylates (2) react with 1,3-diimino isoindoline (3) to afford functionalized 2,6-dihydro[2,1-a]isoindole derivatives (4) and ( 5) in good yields along with N-vinyl isoindoles (6) as by-product (Scheme 1).…”
