Influence of the Br?nsted and Lewis acid sites on the catalytic activity and selectivity of Fe/MCM-41 system

The system Fe2O3/MCM-41, with high iron dispersion, was synthesized in order to introduce Lewis acid sites into the MCM-41 structure. Two calcination atmospheres (inert and oxidant) were used to produce iron nanoclusters with different structural properties. Besides, a silylation treatment was realized on both solids with the aim of neutralizing the Br?nsted acidity associated with the MCM-41 silanol groups. The samples were characterized by atomic absorption spectroscopy, X-ray diffraction at low angles, N2 adsorption, temperature-programmed reduction, Fourier transform infrared spectroscopy, nuclear magnetic resonance of 29Si, and M?ssbauer spectroscopy. The influence of the structural changes of the nanoclusters and the effect of the simultaneous presence of Lewis and Br?nsted acid sites were evaluated studying the product distribution from the α-pinene oxide isomerization reaction. It was determined that the Br?nsted acidity of the Fe/MCM-41 system has not the sufficient acid strength to modify the product distribution which is mainly governed by the Lewis sites.

Formation of 1,2-Dioxolanes from Cyclopropanes

The already known carenols 5 and 7 are obtained by stereoselective oxirane cleavage of (1S,3S,4R,6R)-(+)-3α,4α-epoxycarane (4).Autoxidation of the ketone 8, derived from 7, failed to give any 1,2-dioxolane derivatives. 5 is converted to the hydroperoxide

Studies on the Terpenoids and Related Alicyclic Compounds. XXXII. A Synthesis of Chiral Dimethylcyclopropane Derivatives, Versatile Chiral Synthons for Casbane, Lathyrane, and Ingenane-Type Diterpenoids, from (+)-3-Carene

A synthesis of chiral dimethylcyclopropane derivatives, useful for the synthesis of casbane, lathyrane, and ingenane-type diterpenoids, from easily available (+)-3-carene is described.The silyl enol ether (8) was derived from (-)-cis-4-caranone (7b), which was obtained from (+)-3-carene (6).Ozonolysis of 8 gave 9a and 10.The right half segment (11b) for a synthesis of crotonitenone (3) was formed from 9a in three steps.The epoxide (12) was isomerized to a mixture of the allylic alcohols (13a) and (14a), which was transformed to the ketone (20) in five steps.Methylation of 20 followed by phosphorylation and reduction gave (+)-cis-4-caranone (23) in about 40 percent overall yield from 12.The methylester (+)-(32b) and its enantiomer (-)-(34b) were synthesized from (+)-6.Ozonolysis of a mixture of the silyl enol ether (30) and (31) followed by methylation with diazomethane gave 32a, which was hydrolyzed to give the desired (+)-32b.The enantiomer (-)-34b was derived from 32a in five steps.
