  N- and C-protected derivatives of 2,5-disubstituted trans- and cis-THF amino acids 6 and 7 were prepared in enantiomerically pure form from L-alanine. Felkin–Anh-controlled reduction of the ketone 9 was achieved with a 85:15 diastereoselectivity. Epoxidation of 10 and subsequent intramolecular epoxide opening gave the trans- and cis-THF alcohols 11 and 12, which were further transformed into the corresponding

  ñ -和C ^ -保护的衍生物2,5-二取代反式-和顺-THF氨基酸6和7中，从L-丙氨酸对映体纯形式制备。用Felkin-Anh控制的酮9的还原反应非对映选择性为85:15。环氧化反应的10和随后的分子内环氧化物开环得到反式-和顺-THF醇11和12，这是进一步转化为相应的Ñ -和C ^ -保护的2,5-二取代反式-和顺式-THF氨基酸。构象研究表明，顺式-THF二酰胺34在固态和CDCl 3溶液中为β-转弯模拟物。

  The synthesis of a series of RGD mimetics is described. All compounds consist of a central 2,5-disubstituted tetrahydrofuran core, a variable linker to a guanidino group, and a beta-amino alanine unit to mimic the carboxylic acid. Three types of linkers were investigated: a simple four-atom methylene chain (type A, compounds 14, 15, 16, and 17), a four-atom methylene chain with an additional chiral center, and a nitrogen substituent (type B, compounds 38, 39, and 40), and an amide linker of different length with an additional chiral center (type C, compounds 59, 60, 61 and 62). A variety of compounds were tested as potential integrin antagonists in a receptor binding assay (alpha(IIb)beta(3), alpha(v)beta(3), and alpha(v)beta(5)). The relative and absolute configuration of the chiral centers at the THF ring had a pronounced effect on the binding activity and selectivity Compound 14 proved to be a selective inhibitor of to be a selective inhibitor of to be a selective inhibitor of alpha(IIb)beta(3) (IC50 = 20nM), whereas compound 40 exhibited high activity for binding of alpha(IIb)beta(3) (IC50 = 67 nM) and alpha(v)beta(3) (IC50 = 52 nM).
