KM-01, a brassinolide inhibitor, its production, isolation and structure from two fungi Drechslera avenae and Pycnoporus coccineus

A new brassinolide inhibitor, named KM-01, was isolated from the culture filtrates of two fungal species, Drechslera avenae and Pycnoporus coccineus, and the structure with absolute stereochemistry was elucidated as the fatty acid ester of an eremophilane sesquiterpene, bipolaroxin, based on spectroscopic analysis, chemical degradation, and synthesis of the fatty acid.

Fast and efficient one step synthesis of dienamides

A fast and efficient one-step approach to the synthesis of dienamides is reported. This concise methodology relies on the use of imides as reactive intermediates and allows for the preferential formation of Z,E-dienamides in good yields.
