So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Hyun, Young Eum; Kim, Hong-Rae; Jeong, Lak Shin researched the compound: 2,6-Dichloropurine( cas:5451-40-1 ).Recommanded Product: 5451-40-1.They published the article 《Stereoselective Synthesis of (S)- and (N)-Cyclopropyl-Fused Carbocyclic Nucleosides Using Stereoselective Cyclopropanation》 about this compound( cas:5451-40-1 ) in Journal of Organic Chemistry. Keywords: transition state Simmons Smith cyclopropanation conformation Charette; crystal structure carbocyclic nucleoside stereoselective cyclopropanation synthesis cyclopropyl fused. We’ll tell you more about this compound (cas:5451-40-1).
To determine which sugar conformation is favorable in binding to peroxisome proliferator-activated receptors, the conformationally locked south (S) and north (N) analogs were asym. synthesized using a bicyclo[3.1.0]hexane template. The (S)-conformer was synthesized by employing “”reagent-controlled”” Charette asym. cyclopropanation in a 100% stereoselective manner, whereas the (N)-conformer was stereoselectively synthesized by using “”substrate-controlled”” hydroxyl-directed Simmons-Smith cyclopropanation as a key step. (S)- and (N)-Cyclopropyl-Fused Carbocyclic Nucleosides, e.g. I, were prepared
