  Phenethylamines via Heck arylation of a new vinylamine equivalent

  摘要：

  A new vinylamine equivalent, N-vinyloxazolone 3, has been prepared in three steps and shown to undergo Heck arylation with a variety of substrates. The Heck adducts thus obtained are then converted in one step and high yield to phenethylamine hydrochlorides. As a general synthetic method for preparation of substituted phenethylamines, use of this new reagent is shown to be superior to N-vinylphthalimide in number of steps, regiospecificity, and chemical yield.

  Novel oxazolidin-2-one-linked 1,2,3-triazole derivatives (4a–k) were synthesized by straightforward and versatile azide–enolate (3 + 2) cycloaddition. The series of compounds was screened for antifungal activity against four filamentous fungi as well as six yeast species of Candida spp. According to their efficiency and breadth of scope, they can be ordered as 4k > 4d > 4h > 4a, especially in relation

  for the synthesis of 4-oxazolin-2-ones by a one-pot MW-promoted condensation of α-ketols and isocyanates is reported. An alternative thermal approach using the same starting materials is also described. These cyclic enamides were efficient nucleophiles, reacting with Michael acceptors and prenyl bromide to give a variety of polycyclic structures bearing one or two quaternary stereocenters.
