AbstractA series of compounds possessing a ‘Steroid‐type’ scent and related to 4‐(4′‐t‐butylcyclohexyl)‐4‐methyl‐2‐pentanones (1 and 2) has been synthesized. The odor of these compounds has been found to be dependent on their conformation; only when the molecule can assume a steroid‐like shape there is an interaction with the odor chemoreceptor.

AbstractDer aus der roten Passionsfrucht isolierte Aromastoff (III) kann entweder durch Wittig‐Reaktion aus Verbindung (II) oder durch Thermolyse der leicht darstellbaren Verbindung (VI) erhalten werden.

AbstractDie Photolyse der neu untersuchten Ketone (Ib, n: 5, 6, 8) sowie der bereits untersuchten Vergleichsketone (Ib, n: 3, 4, 7) in Cyclohexan bei 15°C liefert die Alkohole (IIb) sowie die entsprechenden Cyclobutanole (III) (beide stereoisomere Formen) und die ungesättigten Ketone (IV).

AbstractAls Träger des charakterisitischen Cassis‐Flavors werden die zwei Diastereomeren (I) und (II) identifiziert.

AbstractThe diastereoisomeres of p‐menthone‐8‐thiol, derived from (+)‐menthol, are the first ketothiols of the terpene series to have been found in nature. Stereochemistry, methods of preparation and olfactory properties of the new compounds are described.

AbstractThe photolysis of cyclic ketones from C9 to C16 has been carried out, and formation of cyclobutanols observed in only C11 to C16. Although in the mass spectrometer cyclobutanols are not formed, an initial transfer of a γ‐hydrogen atom to the carbonyl group is shown to occur in the mass spectra of all cyclic ketones higher than C10.

Abstract3‐Keto‐tetrahydrothiophen (I) ergibt in Gegenwart von NaH mit Äthylacetat die beiden Acetyl‐Verbindungen (II) und (III) sowie das Isomere (IV).

AbstractA gas chromatographic investigation of the volatile part of a pineapple concentrate led to the identification of 59 substances, 35 of which were not previously found in pineapple. The identifications and syntheses of some esters (Δ3‐ and Δ4‐unsaturated, β‐hydroxy, β‐acetoxy, and δ‐acetoxy) and of a new sulfur compound are given.
