    L-Rhamnal has been transformed into the tetrahydrofuran subunits (14 and 21) of tetronasin (ICI-139603) (1) and tetronomycin (2), in which the three chiral centers at the 2- and 5-positions and the methoxy-bearing carbon are of mirror image.

    Abstract

    Synthesis of assumed natural (12R,13S)-enantiomers of pyriculariol (1) and dihydropyriculariol (2), phytotoxins isolated from rice blast disease fungus, Pyricularia oryzae, was achieved using Wittig reaction or microwave-assisted Stille coupling reaction as the key step. The synthesis revealed that the natural 1 and 2 are racemates. Foliar application test on a rice leaf indicated that both the salicylaldehyde core and side chain were necessary for phytotoxic activity. The fungus is found to produce optically active phytotoxins when incubated with rotary shaker, but racemic ones when cultured using an aerated jar fermenter.

    摘要

    使用Wittig反应或微波辅助的Stille偶联反应作为关键步骤,合成了米瘟病菌Pyricularia oryzae分离的植物毒素pyriculariol(1)和dihydropyriculariol(2)的假定天然(12R,13S)对映体。合成表明,天然1和2是外消旋体。在水稻叶上进行叶面喷施试验表明,水杨醛核心和侧链均对植物毒性活性必不可少。当使用旋转摇床进行孵育时,真菌会产生光学活性的植物毒素,但是使用通气罐发酵器培养时则产生外消旋体。

    8-dimethoxy-1-naphthol, prepared from the lithiation and benzyne formation from 1,4-difluoro-2,5-dimethoxybenzene and Diels-Alder cycloaddition with furan, was sequentially C-glycosidated under Suzuki conditions and O-glycosidated using di-O-acetyl-L-rhamnal to provide the corresponding beta-naphthyl C,O-disaccharide. Further lithiation, benzyne formation, and cycloaddition with furan gave an oxa-bridged 1,

    First total synthesis of (−)-pyriculariol, a phytotoxin isolated from rice blast fungus, Magnaporthe grisea, was achieved to determine the absolute configuration of the natural product to be 5′R,6′S. The key step was Stille coupling reaction using microwave irradiation from −78 °C to control the reaction.
