  • Decades of synthesis and application of spiro cyclopropanes
    Benzylidenecyclopropane, in which the exocyclic double bond is conjugated with the aromatic ring, is capable of adding two molecules of 4-phenyl-3 H -1,2,4-triazole-3,5 (4 H)-dione to give 2,10-diphenyl-5,7,13,13a-tetrahydro-1 H,9 H -7,13-etheno [1,2,4]triazolo [1′,2′:1,2]pyridazino [4,5-c] [1,2,4]triazolo [1,2-a]pyridazine-1,3,9,11 (2 H,10
  • Diastereoselective synthesis of spiro [cyclopropane-1,3 . . .
    Transition metal-free diastereoselective cyclopropanation of 3-methyleneindolin-2-ones using tosylhydrazone salts as a safe alternative to diazo-compounds was achieved in high yields
  • A convenient cyclopropanation process of oxindoles via . . .
    The most notable methods for the preparation of spirocyclopropyl oxindoles directly from indoles are as follows: 1) cyclopropanation of unprotected indoles with 1,2-dibromoethane under strongly alkaline conditions, then deprotection of N-substituted spirocyclopropyl oxindoles with metal Mg (Scheme 2 a) [11]; 2) N-substituted spirocyclopropyl

  • Organic Syntheses Procedure
    The resulting orange solid is then further dried by high vacuum (3 mmHg) for 2 5 h to afford methyl spiro [cyclopropane-1,9'-fluorene]-2-carboxylate (4) (55 45 g, 84%) (Notes 23, 24, and 25) as an orange solid, which is used in the next step without further purification (Figure 6B) (Note 26) Figure 4
