Acetalization of 1-2 and 1-3 diols, even as sterically crowded as chloramphenicol, by carbonyl derivatives with substituents of various sizes has been performed at room temperature under mild conditions, by using heterogeneous catalysis (sulfonated polystyrene) in the presence of mol. sieves. Several new acetals of chloramphenicol e.g. I, have thus been obtained in good yields, isolated and characterized.

The rate constants were determined for the acid hydrolysis of the 10 cyclic acetals obtained by condensation of (CH₂OH)₂ and MeCH(OH)CH₂OH with the following ketones: Me₂CO, MeEtCO, Et₂CO, cyclohexanone, and cyclopentanone. Measurements made by direct dilatometry and calculated with a computer were extremely precise, but the results indicated that the reaction had only limited interest from the point of view of conformational analysis.

MacLeod, Glesni published the artcileSubstituted 4-methyl-1,3-dioxolanes: solvent interaction products in some commercial beef flavorings, Synthetic Route of 1193-11-9, the publication is Journal of Agricultural and Food Chemistry (1980), 28(2), 441-6, database is CAplus.

Using a modified Likens and Nickerson extraction procedure followed by low-temperature/high-vacuum distillation representative samples of aroma volatiles were obtained from some com. beef flavorings. Prefractionation of concentrates by preparative gas chromatog. facilitated subsequent anal. by combined gas chromatog.-mass spectrometry. One fraction provided a number of similar mass spectra with intense characteristic peaks at m/e 87. These could be 2-substituted-4-methyl-1,3-dioxolanes, but dioxolanes have not been reported as volatile components of meat. Selected 1,3-dioxolanes were synthesized and comparison of their mass spectra and gas-chromatog. retention times confirmed the identities of the unknown components of the simulated meat flavor isolate. Their origin may be explained by interaction of 1,2-propanediol [57-55-6], a commonly used solvent for com. flavors, with carbonyl aroma components, interactions which can modify the flavor characteristics of the product.

γ-Radiolysis of MeOCH₂CH₂OMe gave MeOCH•CH₂OMe, which decomposed to HCOCH₂• and Me₂O. Radiolysis of I (R = H, R¹ = Me; R = R¹ = Me) gave a cyclic radical, which decomposed to RCOCH•R¹ and Me₂CO. Synchronous cleavage of 2 bonds β to the initially formed radical was proposed.

The effects of water activity (a_w) on the major volatiles produced from a meat flavor model system containing monosodium-L-glutamate  [142-47-2], L-ascorbic acid  [50-81-7], thiamin-HCl  [67-03-8], and cystine  [56-89-3] were investigated. Quant. and qual. differences in volatiles produced between high and low a_w systems (heated at 135°) were found. Qual. changes were observed to occur at about a_w 0.4. Compounds identified in high and low a_w systems fell into classes which are associated with boiling and roasting cooking techniques (resp.) of known naturally occurring compounds
