  Synthesis and biological evaluation of some stilbene derivatives

  摘要：

  Several trans and cis stilbenes with substitution on the olefinic bridge were synthesized and characterized by IR, NMR and mass spectroscopy in an effort to obtain substances that could be more readily formulated. All the synthesized compounds were screened against Molt4/C8, CEM and L1210 cell lines. None of these compounds were endowed with pronounced cytostatic activity. However, Schiff derivatives emerged as cytostatic agents (IC(50): 0.77-10 mu g/ml) that deserve further investigation.

  A RhIII‐catalyzed intramolecular oxidative cross‐coupling between double bonds for the synthesis of macrolides is described. Under the optimized reaction conditions, macrocycles containing a diene moiety can be formed in reasonable yields and with excellent chemo‐ and stereoselectivity. This method provides an efficient approach to synthesize macrocyclic compounds containing a 1,3‐conjugated diene

  Reported herein is a practical method for macrolactam synthesis via a Rh(III)-catalyzed ring closing alkene–alkene cross-coupling reaction. The reaction proceeded via a Rh-catalyzed alkenyl sp2 C–H activation process, which allows access to macrocyclic molecules of different ring sizes. Macrolactams containing a conjugated diene framework could be easily prepared in high chemoselectivities and Z,E

  An efficient entry into pyrazol-3-ones is described starting from propenoic acids that were first transformed into the corresponding hydrazides. Oxidation of the hydrazides gave the diazenes and the latter cyclized to pyrazol-3-ones on treatment with ZrCl4. The methoxycarbonyl protection of the N-1 of the pyrazolone derivatives was easily removed under mild reaction conditions.

  A Pd0‐catalyzed asymmetric Nazarov‐type cyclization is described. The optimized ligand for the reaction incorporates a weakly coordinating pyridine ring into a TADDOL‐derived phosphoramidite (TADDOL=α,α,α,α‐tetraaryl‐1,3‐dioxolane‐4,5‐dimethanol). The reaction leads to the formation of cyclopentenones as single diastereoisomers that incorporate two contiguous asymmetric centers, one tertiary and one

  描述了Pd 0催化的不对称Nazarov型环化反应。该反应的优化配体将弱配位吡啶环掺入TADDOL衍生的亚磷酰胺（TADDOL =α，α，α，α-四芳基-1,3-二氧戊环-4,5-二甲醇）。该反应导致形成单一非对映异构体的环戊烯酮，以高收率和光学纯度结合了两个连续的不对称中心，一个叔碳原子中心和一个全碳原子的四元立体中心。值得注意的是，该反应不需要底物应被芳基取代基活化。
