Stereoselective synthesis of ptilocaulin and its 7-epimer

A versatile stereoselective synthesis of ptilocaulin 1 and its 7-epimer 22, involving formation of the B-ring by intramolecular nitrile oxide cyclization, is described.

Fragrant mixtures containing esters and ketones

The invention relates to fragrant mixtures comprising at least one compound of general formula (I), a method for producing claimed fragrant mixtures, particularly perfume oils, perfumed products containing the claimed fragrant mixture, and the use of the compound of general formula (I) to strengthen the natural freshness and/or emanation and/or to mask or reduce greasy and/or metallic notes of one or more fragrant substances that differ from the compound of formula (I).

Asymmetric allylic alkylation of ketone enolates: An asymmetric claisen surrogate

(Chemical Equation Presented) The combination of catalytic palladium(0) and Trost ligand provides an effective catalyst for the rearrangement of allyl β-ketoesters. The mechanism of the transformation involves formation of π-allyl palladium intermediates which undergo enantioselective attack by ketone enolates. Decarboxylation of β-ketocarboxylates allows regiospecific generation of enolates under extremely mild conditions.

Ketone-directed peracid epoxidation of cyclic alkenes

Ketone carbonyl groups are shown to direct the peracid epoxidation of cyclic alkenes with greater selectivity than that displayed by esters. An 18O labelling study is used to show that a dioxirane intermediate is not involved in these reactions.
