RCM-Mediated Synthesis of Trifluoromethyl-Containing Nitrogen Heterocycles
摘要:
A ring-closing metathesis mediated pathway to trifluoromethyl-containing piperidines is detailed. This involves the development of a synthetic route to a new (trifluoromethyl)allylating reagent via a Diels-Alder/retro-Diels-Alder strategy, its application in the synthesis of a series of trifluormethyl-substituted diolefin precursors for ring-closing metathesis, and eventually the successful cyclization of these precursor molecules into the corresponding functionalized piperidines.
Facile Allylation of N‐Boc and N‐Cbz Imines with Allyltrichlorosilane promoted by DMF
摘要:
Facile allylation of various N-Boc and N-Cbz imines with allyltrichlorosilane has been effected using N,N-dimethylformamide (DMF) as the activator. The N-Boc and N-Cbz homoallylic amines were obtained in good to high yields under mild conditions.
