  Base-Catalyzed Endo-Mode Cyclization of Allenes:  Easy Preparation of Five- to Nine-Membered Oxacycles

  摘要：

  A reliable and efficient procedure for constructing five- to eight-membered oxacycles has been developed. Allenes with both a phosphoryl group and a suitable delta-hydroxyalkyl side chain at the Cl-position underwent an endo mode ring-closing reaction to give five- to seven-membered oxacycles. Changing the phosphoryl group to a phosphono functionality facilitated the preparation of eight-membered congeners. Introduction of a cis double bond to the alkyl side chain of the starting allenes made possible the easy formation of medium-sized oxacycles, such as the dihydrooxocin and tetrahydrooxonin frameworks, regardless of the electron-withdrawing group (POPh2, PO(OEt)(2), SOPh, and SO2Ph) at the C-1-position.

• Use of the transannular Diels–Alder (TADA) reaction to probe biological receptors: Rational design and synthesis of tricyclic TADA adducts capable of rigidly holding pharmacophore parts

  Transannular Diels–Alder (TADA) adducts constitute a collection of rigid structures, whose conformational diversity is rich. It is possible to design such specifically functionalized molecules capable of binding to known biological targets by molecular modelling MCSS–HOOK (multiple copy simultaneous search). Here we show that such carefully designed compounds can be easily built from small synthons. TADA adducts are very interesting due to their huge conformational diversity, their rigidity (biological interest), and their ease of synthesis (chemical interest).Key words: tricycles, synthesis, transannular Diels–Alder, macrocyclization, conformation, diversity.

  横向二烯-阿尔德（TADA）加合物构成了一系列刚性结构，其构象多样性丰富。通过分子建模MCSS-HOOK（多重拷贝同时搜索），可以设计出能够结合已知生物靶点的特定功能化分子。在这里，我们展示了这样精心设计的化合物可以很容易地由小合成子构建。TADA加合物非常有趣，因为它们具有巨大的构象多样性、刚性（生物学上的兴趣）和易于合成（化学上的兴趣）。关键词：三环、合成、横向二烯-阿尔德、大环化、构象、多样性。
