Influence of liquid crystalline formation on the phase behavior of side-chain liquid crystalline block copolymers

Ji, Liangliang,Chen, Xiaofang,Wu, Yanhong,Yang, Xiaoming,Tu, Yingfeng

, p. 147 - 154 (2015)

A series of narrowly distributed diblock copolymers composed of amorphous components and side-chain liquid crystalline (LC) polymer, poly (butyl acrylate)-block-poly [8-(4-cyano-4′-biphenyl)-1-octanoyl acrylate] (PBA-b-PCBOA), with side-chain LC block weight fraction (fw,PCBOA) ranging from 25% to 87%, were synthesized by atom transfer radical polymerization (ATRP). Their thermal property, LC behavior, bulk phase behavior and thin film morphology were studied by differential scanning calorimetry (DSC), polarizing optical microscope (POM), small-angle X-ray scattering (SAXS) techniques and atomic force microscopy (AFM), respectively. The results show the diblock copolymers with different composition could present sphere, lamellar and cylinder morphologies before the order-disorder transition. As the mesogen units self-organize to form smectic phase, the lamellar morphology dominates during the majority LC block weight fraction range (fw,PCBOA = 46%-77%) to minimized the surface energy. Interestingly, for spin-coated thin film, the lamella phase separation size decreased with increasing annealing time. For the copolymer with fw,PCBOA of 67%, a thermoreversible order-order transition (OOT) and lamella to lamella/modified layer (L/ML), were observed.

Chemoenzymatic synthesis of (R)-(+)-2-methylbutan-1-ol, a chiral synthon for the preparation of optically active pheromones

Geresh, Shimona,Valiyaveettil, Thomas J.,Lavie, Yair,Shani, Arnon

, p. 89 - 96 (1998)

Optically active (R)-(+)-2-methylbutan-1-ol (which is not commercially available) was prepared by a chemoenzymatic synthesis, in which the key step involved a reduction catalyzed by baker's yeast. The synthon was used in the synthesis of (R)-10-methyldodecan-1-yl acetate, the chiral methyl-branched pheromone of Adoxophyes sp.

Identification and synthesis of the male produced volatiles of the carrion beetle, Oxelytrum erythrurum (Coleoptera: Silphidae)

Fockink, Douglas H.,Martins, Camila B.C.,Zarbin, Paulo H.G.

, p. 5353 - 5356 (2015)

Necrophagous beetles belonging to the family Silphidae are recognized as potentially useful in forensic investigations (to estimate post mortem interval). Gas chromatography analyses of extracts of aerations of adult Oxelytrum erythrurum revealed the presence of two male-specific compounds. These compounds were identified as (Z)-1,10-nonadecadiene (major) and 1-nonadecene (minor) using microderivatizations of the natural male extract, such as hydrogenation, partial reduction and methylthiolation, mass spectrum comparisons, and co-injections with authentic standards. Both compounds might be components of a pheromone responsible for sexual communication in this species.

Nucleophilic substitution reactions of unbranched alkyl amines using triazine reagents

Kitamura, Masanori,Kitaoka, Yuki,Fujita, Hikaru,Kunishima, Munetaka

supporting information, (2022/03/02)

Since amines are present in many organic, biological, and drug molecules, a strategy of synthesizing desired compounds by nucleophilic substitution reactions of these amines is very attractive. By using triazine reagents, we have found that nucleophilic substitution reactions of unbranched alkyl amines via morpholine derivatives are feasible. This method can be performed under milder reaction conditions than those in previously reported methods.

Practical Synthesis and Field Application of the Synthetic Sex Pheromone of Rice Stem Borer, Chilo suppressalis (Lepidoptera: Pyralidae)

Chien, Wei-Jynn,Gupta, Sachin,Liu, Bin,Lou, Da Wei,Shen, Yu-Jhe,Syu, Kun-Jie,Tseng, Jui-Chang,Zhang, Yuan-Xin

, (2020/03/11)

Rice stem borer, Chilo suppressalis, is a common and major serious pest of rice, maize, and wheat crops across Asia, Europe, and Oceania countries. Its sex pheromone consists of three analogously compounds, i.e., (Z)-hexadec-11-enal (1), (Z)-octadec-13-enal (2), and (Z)-hexadec-9-enal (3), as long-chain aliphatic internal cis-alkenyl aldehydes. In order to perform an economic and widespread pest control management of rice stem borer, a versatile and efficient synthetic strategy is required. A versatile and efficient synthesis using a common synthetic route for cis-alkenals with high overall yields is described. Commercially available inexpensive aliphatic diols were chosen as starting materials. Two key steps were employed to synthesize the long-chain aliphatic internal cis-alkenes in excellent yields, including the alkylation of terminal alkynes without the utilization of a highly polar aprotic cosolvent and the versatile cis-selective semihydrogenation for the reduction of internal alkynes with excellent stereoselectivity. The results of field tests showed that the synthetic sex pheromone blend was highly effective for the capture of rice stem borer.

The synthesis method has the advantages of high availability of raw materials, high yield and good selectivity, and is suitable for industrial production.

Simple synthesis method for sex pheromones of oriental fruit moths

-

Paragraph 0023-0025, (2019/06/27)

The invention belongs to the field of chemical synthesis, and particularly relates to a simple synthesis method for sex pheromones of oriental fruit moths. The method includes subjecting 1,8-octandiolas a raw material to unilateral bromination reaction to obtain 8-bromooctanol, reacting the 8-bromooctanol with triphenylphosphine to obtain 8-hydroxyoctyl triphenylphosphonium salt, subjecting the 8-hydroxyoctyl triphenylphosphonium salt and n-butanal to Wittig reaction under the action of an alkali to obtain (Z/E)-8-dodecene-1-alcohol, and performing acetylation under the action of pyridine andacetic anhydride to obtain a target product. The cis-trans ratio of enol obtained after the Wittig reaction ranges from 91.8:8.2 to 92.9:7.1; within the optimal attraction range, and by strictly controlling the amount of the acetic anhydride, the properly proportioned sex pheromones of the oriental fruit moths can be obtained according to a 'one-pot' method.
