  摘要：

  据报道，外消旋烯酰胺的设计、合成和双不对称氢化可用于番茄酸及其异构体的立体发散合成。氢化结果（产率，ee）用于识别匹配和不匹配的产物，该信息对于阐明反应机理非常重要。还提出，如果反应机理已知，则无需通过匹配/不匹配分析进行光谱分析即可鉴定产物的结构。

  5,5-Bis(hydroxymethyl)tetrahydro-2-furanone and its isomer 4,4-bis(hydroxymethyl)tetrahydro-2-furanone were investigated as possible templates for the construction of conformationally constrained analogues of the biologically important second messenger, diacylglycerol (DAG). The former lactone contains embedded within its structure an exact glycerol moiety, while in the latter the ring oxygen has been transposed to the other side of the carbonyl group. Al target compounds were synthesized as racemates from 1,3-dihydroxy-2-propanone. The 5,5-bis(hydroxymethyl)tetrahydro-2-furanone proved to be the better template for the construction of DAG surrogates that were demonstrated to have high binding affinities for the biological target, protein kinase C (PK-C). The simplest target compounds derived from this template (3e and 3f) have one of the hydroxyl moieties functionalized either as a myristate or as an oleate ester. The simplest target compound (9e) derived from the ineffective 4,4-bis(hydroxymethyl)tetrahydro-2-furanone template was investigated only with a myristoyl acyl chain. Reducing the long acyl chain to an acetyl moiety and attaching a compensating lipophilic chain to the lactone ring as an alpha-alkylidene moiety produced compounds 10e and 10f(Z-isomers) and 11e and 11f(E-isomers), which were constructed on the more effective 5,5-bis(hydroxymethyl)tetrahydro-2-furanone template. Targets 14c (Z-isomer) and 15c (E-isomer) were derived, in turn, from 4,4-bis(hydroxymethyl)tetrahydro-2-furan. The affinities of these ligands for PK-C were assessed in terms of their ability to displace bound [H-3-20]phorbol 12,13-dibutyrate (PDBU) from the single isozyme PK-C alpha. The biological data support the hypothesis that the increase in binding affinity for PK-C shown by some of these constrained DAG mimetics appears to be entropic in nature. Two of the designed ligands (10e and 10f) showed the highest affinities (34 and 24 nM, respectively) reported so far for a DAG analogue. Assuming that the interaction between these racemic compounds and PK-C is stereospecific, the potency of the active enantiomer is anticipated to double.
