comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولSynthesis of the C1-C21 (C1'-C21') fragment of the dimeric polyketide natural product SCH 351448.
[structure: see text] A convergent, stereoselective assembly of the C1-C21 (C1'-C21') fragment of SCH 351448, a 28-membered bis-lactone natural product, has been developed. A highly efficient approach to this fragment assembles 75% of the carbon skeleton and all the stereochemical elements present in the natural product. In addition, an interesting boron ligand effect on the diastereoselectivit...
متن کاملSynthesis of a fully functionalized protected C1-C11 fragment for the synthesis of the tedanolides.
[figure: see text] The use of several non-aldol aldol processes allows one to prepare a fully functionalized and completely protected C1-C11 fragment that should be useful for the total synthesis of the tedanolides.
متن کاملStrategies for the total synthesis of C2-C11 cyclized cembranoids.
The C2-C11 cyclized cembranoids, which include the eunicellins (also known as the cladiellins), briarellins, asbestinins, and sarcodictyins, are secondary metabolites isolated from gorgonian octocorals and soft corals. An unusual oxatricyclic ring system containing a hydroisobenzofuran and an oxonene unit with stereogenic centers residing at C1-3, 9, 10, and 14 is common to the eunicellins, bri...

چکیده پلاتین، فلزی نجیب، پایدار و گران قیمت با خاصیت کاتالیزوری زیاد است که کاربرد های صنعتی فراوانی دارد. کمپلکس های پلاتین(ii) به عنوان دارو های ضد سرطان شناخته شدند و در شیمی درمانی بیماران سرطانی کاربرد دارند. خاصیت کاتالیزوری و عملکرد گزینشی پلاتین مستقیماً به اندازه و- شکل ماده ی پلاتینی بستگی دارد. بعضی از نانو ذرات فلزی در سطح مشترک مایع- مایع سنتز شده اند، اما نانو ساختار های پلاتین ب...
