Novel Resorcinol Derivatives from Lasiodiplodia theobromae
نویسندگان
چکیده
Two novel resorcinol derivatives were isolated from the mycelium of Lasiodiplodia theo bromae IFO 31059 as potato micro-tuber inducing compounds. Their structures were estab lished by spectroscopic methods as ethyl (6 ' 7?)-2,4-dihydroxy-6-(6'-hydroxyheptyl)benzoate (8) and isobutyl (6 ' /?)-2.4-dihydroxy-6-(6'-hydroxyheptyl)benzoate (9). The absolute stereo chemistry of the asymmetric center of (8) was determined by an advanced Mosher method.

متن کاملLasiodiplodia theobromae is a Mycoparasite of a Powdery Mildew Pathogen
Powdery mildews on over 40 plants in Bangalore were screened during July-December of 2003~2008. Isolates from mycoparasitised Oidium caesalpiniacearum of Bauhinia purpurea comprised Lasiodiplodia theobromae, in addition to Ampelomyces quisqualis. Koch's postulates were satisfied to establish the mycoparasitism of L. theobromae. This is the first report that L. theobromae acts as a mycoparasite ...

متن کاملIsolation and structural elucidation of a new cyclohexenone compound from Lasiodiplodia theobromae.
A new cyclohexenone compound was isolated as a mixture of enantiomers from a culture filtrate of Lasiodiplodia theobromae. The relative structure was determined to be 4,5-dihydroxy-3-methyl-cyclohex-2-enone on the basis of MS, (1)H-NMR, and (13)C-NMR spectroscopic analyses, including 2D-NMR experiments. Resolution of the enantiomers was conducted by a coupling reaction with (S)-MTPA-Cl followed...
