Antheridium-inducing factor

H NMR and infrared spectral data of ( )-B, ( )-B methyl ester, and ( )-B methyl ester 3-benzoate were identical with those of AAn and the corresponding derivatives. Mass spectra of the methyl esters of ( )-B and AAn were identical. Chromatographic mobility of ( )-B relative to gibberellic acid (GA3) (as standard) was identical with that reported for AAn. Therefore, this synthesis also proved that antheridium inducing factor, AAn, must be regarded as possessing stereostructure B rather than A as originally supposed.
