Design and synthesis of angularly annulated spirocyclics via enyne metathesis and the Diels-Alder reaction as key steps

We have developed a simple and an efficient route to a range of angularly fused spirocycles by the application of enyne metathesis and the Diels-Alder reaction as key steps. The enyne metathesis protocol has been further extended to the dibenzylation of indane-1,3-dione by using cross-enyne metathesis in the presence of hexa-1,5-diene with the aid of Grubbs' 1st generation catalyst followed by an aromatization sequence with DDQ.

Synthesis and Reactions of 9,10,11-Triptindantrione and Some Other Functionalized Tribenzopropellanes (9H,10H-4b,9a-(Benzenomethano)indenoindenes

A new and efficient route to the tribenzopropellane 1 (triptindan) and to some interesting derivatives such as 9-triptindanone (13) and 9,10,11-triptindantrione (3) has been developed.The propellane framework of 13 is accessible from 1,3-indandione in only two steps.Triketone 3, a versatile substrate with formal C3v molecular symmetry, is obtained from 13 in two further steps.First examples are presented for reactions of 3 leading to more complex benzoannelated centropolyquinanes (centropolyindans).

Chemical Reactions in Microemulsions: Application of Microemulsions as Solvents for Organic Synthesis

In this paper, microemulsions are studied as media for reactions between reactants of very different solubility.In particular, the reaction of 1-bromooctane with iodide is dealt with as a model reaction.The phase behaviour of the microemulsion changes when the reactants are added and the progress of the reaction changes the concentration of the species involved.A number of standard reactions were also performed in microemulsions, for example nucleophilic substitutions, hydrolysis of esters, oxidation of an alcohol, reduction of an aldehyde, and reactions of active methylene compounds.A comparison of different solvents is done on the basis of the rate constants of three different reactions carried out in a microemulsion, in ethanol, in DMF and by phase-transfer catalysis.

Chemical Reactions in Microemulsions: Kinetics of the Alkylation of 2-Alkylindan-1,3-diones in Microemulsions and Polar Organic Solvents

The kinetics of the alkylation of 2-alkylindan-1,3-diones by benzyl bromide has been studied in microemulsions and polar organic solvents.In microemulsions the reaction proceeds at the microscopic water/oil interface.The solvent properties of this interfa
