Codsiga:

Ytterbium (III) Trifluoromethanesulfonate Hydrate (CAS: 54761-04-5) waxay u shaqeysaa sidii kicinta isku dhafka dabiiciga ah ee heterocycles.Sidoo kale waxay u shaqeysaa sidii asiidh Lewis oo ah falcelinno dabiici ah oo kala duwan.Keliya biraha dhifka ah ee dhulka ee isku dhafan ee isku-dhafka dabiiciga ah.Biyo-qaade u adkaysta Lewis acid ayaa dhawaan loo adeegsaday isku-dhafka hal-dhari ee β-lactams, iyo falcelinta isugeynta ee nucleophilic ee la xakameeyey.Waxay katalaystaa isku-dhafka deoxypenostatin A ee sheeko cusub, stereoselective, falcelinta Diels-Alder intramolecular.Kataliye Lewis acid loo isticmaalo silyated chinchona alkaloid ee isku xidhka asymmetric ee β-lactams laga beddelay koloride acid iyo aryl imine.Waxa kale oo loo isticmaalaa in lagu kiciyo falcelinta aldehyde-ene ee isku xidhka qalfoofka guaiane.Qayb muhiim ah oo ka mid ah aashitada Lewis ee kala duwan ee falcelinta synthetic, oo ay ku jiraan allylborations.
