TL;DR: In this paper, the structure of momilactone-C (M-C), a minor constituent of growth inhibitors in rice husk, was determined by X-ray analysis, which revealed that C9-C10 of M-C was unusual cis configuration having a boat conformation of A ring.
Abstract: Structure of momilactone-C (M-C), a minor constituent of growth inhibitors in rice husk, was determined by X-ray analysis, which revealed that C9–C10 of M-C was unusual cis configuration having a boat conformation of A ring. The stereochemistry of C9 of previously reported momilactone-A and B (I and II) has been erroneously written and should now be revised to β -configuration with respect to hydrogen atom as in M-C.
