A efficient methodology allowing the one-pot stereoselective synthesis of alpha-fluoroacrylates, based on the addition of ethyl dibromofluoroacetate to a carbonyl derivative using diethylzinc as organometallic mediator, is described. Two different pa

Thieno [2,3-b] pyridine derivatives, functionalized on the thiophene ring have been synthesized in two different ways: electrophilic substitution of thieno [2,3-b] pyridine derivatives or construction of a pyridine ring starting from disubstituted th

L’orthodontiste peut etre confronte sans le savoir a un patient atteint de dysfonctionnement cranio-mandibulaire. Ce patient n’est pas forcement un adulte, il peut etre, soit un enfant, soit un adolescent. Le piege est tendu surtout quand les sig

Without realizing it, orthodontists may find themselves treating patients suffering from cranio-mandibular disorders, who may be adults, but not necessarily. Both young children and adolescents can also have these problems. Orthodontists often fall i

The readily available S-(tert-butyl)-N-(trimethylsilyl)-S-phenylsulfoximine was prepared from S-methyl-N-(trimethylsilyl)-S-phenylsulfoximine via lithiation-methylation sequences. The reaction with n-butyllithium in THF at −78°C afforded the corre

The synthesis of NADH models in the pyrrolo[2,3- b ]pyridine series bearing one or two chiral auxiliaries either at the pyridine or at the pyrrole ring is described. These models were involved in the reduction of methyl benzoylformate. The reactivity
