Functional group transformations of diols, cyclic ethers, and lactones using aqueous hydrobromic acid and phase transfer catalyst under microwave irradiation

Synthesis of bromoalkanols has been achieved from diols, ethers, and lactones using aq HBr (48%) and tetrabutylammonium iodide/bromide as phase transfer catalyst under microwave irradiation. This environmentally benign route provides enhanced yields of products and does away with the use of benzene as compared to existing conventional methods.

A new method for the synthesis of polymerizable ionic liquids bearing a methacrylate moiety was developed with the aim to avoid premature polymerization of synthesized compounds. Spacer length between the imidazolium cation and the polymerizable functional group varied from 2 to 10 carbon atoms. Different 1-(n-hydroxyalkyl)-3-methylimidazolium bromides and 1-[n-(methacryloyloxy)- alkyl]-3-methylimidazolium bromides were obtained with very good yields (more than 90%).

According to our retrosynthesis, the main chain of the target molecule could be constructed using a C5?+?C7?+?C5 strategy. The key induction reaction afforded chiral methyl group moieties using different Evans templates with different configurations. Li2CuCl4 was effectively employed in the Csp3[sbnd]Csp3 coupling protocol. The target molecular was obtained in a 12.6% overall yield with nine steps in the longest linear route.
Parthenogenesis, calling behavior, and insect-released volatiles of leafminer moth Phyllonorycter emberizaepenella.

We proved that the leafminer moth Phyllonorycter emberizaepenella (Lepidoptera: Gracillariidae) reproduces by parthenogenesis of the thelytoky type. Despite a complete absence of males, parthenogenetically reproducing females diurnally demonstrated the calling posture normally used for releasing signaling compounds. Two compounds, which we collected from a calling female, were identified as potential sex pheromone components: (8E, 10E)-8,10-tetradecadienyl acetate and (8E,10E)-8,10-tetradecadienol, the latter occurring only in trace amounts. In field experiments, no males were attracted to traps baited with either the potential sex pheromone or with virgin females. Both the pattern of behavior and the chemical characteristics of the pheromone of Ph. emberizaepenella species were similar to those known for Lepidoptera with the usual amphimictic mode of reproduction. Theoretical speculations that in thelytoky, where there is no need to find a sexual partner, the individuals would obtain certain advantages due to reduction in their sexual behavior, were, thus, not confirmed for Ph. emberizaepenella.
An Effective Method for the Preparation of ω-Bromoalkanols from α,ω-Diols

Pure ω-bromoalkanols 2 (n=2-12), not contaminated by any dibromoalkanes or unreacted diols 1, were prepared in good yields by refluxing a mixture of diols 1, aqueous (48percent) hydrogen bromide, and benzene using a Dean-Stark water separator.
Synthesis and field evaluation of methyl-branched ketones, sex pheromone components produced by lithosiinae female moths in the family of arctiidae

Female moths of Lyclene dharma dharma (Arctiidae, Lithosiinae) produce a novel sex pheromone composed of three methyl-branched ketones (I-III) in a ratio of 2: 1: 1. In order to confirm the structure of III (6, 14- dimethyl-2-octadecanone), a mixture of its four stereoisomers was synthesized via chain elongation by two Wittig reactions, starting from 1, 7-hexanediol. GC-MS data of the synthetic III were satisfactorily coincident with those of the natural component. In addition to the racemic mixtures of I (6-methyl-2-octadecanone) and II (14-methyl-2-octadecanone), previously synthesized, the activity of III was evaluated in the Iriomote Islands, and effective male attraction was observed for the 2: 1: 1 mixture of I-III. This result indicates that the females do not produce only one stereoisomer for each component or that the response of the males is not disturbed by the other stereoisomers of natural isomers produced by the females. The field test also revealed that the twocomponent lure of I and II captured as many males as the mixture of I-III, while lures baited with two components in other combinations and with only one component scarcely exhibited any male attraction ability.

The combination of androgen receptor antagonists with histone deacetylase inhibitors (HDACi) has been shown to be more effective than antiandrogens alone in halting growth of prostate cancer cell lines. Here we have designed, synthesized and assessed a se

The total syntheses of three C37 methyl-alkenones with different degrees of unsaturation and of their 13C-labelled analogues from commercially available starting materials are presented herein for the first time. These molecules are important to improve the reliability of the measurements and reconstructions of the sea surface temperature and salinity.
