A series of novel N-（4-（2-aryloxythiazol-5-yl）but-3-yn-2-yl）benzamide derivatives were designed and synthesized. Their structures were identified by IH NMR and elemental analyses. Preliminary bioassays indicated that some title compounds provided 〉 80% control of Selerotinia selerotiorum at 50 μg/mL and 〉 70% herbicidal activities against B. campestris at 1.0 μg/mL. Their structure-activities relationships were also discussed.

A modified total synthesis of cystothiazole A is described. In this synthetic strategy, a one-step transformation of acylated oxazolidinone to β-ketoester has been successfully applied, thus making the synthetic route more efficient. This method may also be potentially applied in synthesis of other related β-substituted-β-methoxyl acrylates (bb-MOAs).

Three series of novel 2-cyanoacrylates 7a--7f, 9a-9f, 1.a--1.f containing 1.3,4-thiadiazole ring moieties were synthesized as herbicidal inhibitors of photosystem II （PS II） electron transportation. Their structures were clearly verified by lH NMR, 1.C NMR, elemental analysis （or HRMS analysis） and single-crystal X-ray diffraction analysis. Bioassay showed that a suitable group at the 3-position of acrylates was essential for high herbicidal activ- ity. In particular, compound 7e showed the best herbicidal activities and gave 1.0% inhibitory activity against rape and amaranth pigweed at a dose of 1.5 kg/ha. Introduction of substituent with higher polarity such as sulfinyl or sulfonyl to the 5-position of 1.3,4-thiadiazole decreased herbicidal activities.

Double carbohelicenes have attracted considerable attention due to their aesthetic structures, distinct π-conjugation extension, inherent chirality, and intriguing optical and electronic properties. Herein, the concise de novo synthesis of a new double[5]carbohelicene 1.together with its chiroptical properties, isomerization process and lasing application is presented. 1.was synthesized by a simple protocol involving the formation of a 6,6′-bipentacene as the key intermediate. It is worth noting that1.existed as two diastereomers 1.PP/MM and 1.PM, which were successfully isolated and unambiguously confirmed by Xray crystallography. The optical resolution of the racemic 1.PP/MM was successfully achieved by chiral-phase highperformance liquid chromatography（HPLC）, and 1.PP and 1.MM were characterized by circular dichroism. Interestingly, it was found that 1.PP/MM could be completely isomerized to 1.PM upon heating, and the detailed thermodynamics and kinetics of the isomerization process were systematically investigated. 1.PM exhibited deep-red luminescence with emission maximum at 723 nm and fluorescence quantum yield as high as 32.95%. Consequently, we can showcase the lasing application of 1.PM by doping with epoxy resin to assemble a bottle microlaser spontaneously, which the lasing wavelength is 796.6 nm at a threshold of 0.8 m J cm-2. We believe that our studies, including the facile synthesis methodology, detailed isomerization studies, and lasing application, will shed some light on the design and synthesis of novel carbohelical systems with more functions.
