N-BOC-3-羟基-L-酪氨酸甲酯 | methyl (S)-2-(tert-butoxycarbonylamino)-3-(3,4-dihydroxyphenyl)propanoate | 37169-36-1 | C15H21NO6 | 311.335 |
The close genetic relationship of the mushrooms Retiboletus griseus and R. nigerrimus is supported by the occurrence of the orange-yellow retiboletic acid, resp. its methyl ester, in both species. The structures of these highly substituted pulvinic acid derivatives have been elucidated by spectroscopic investigations. R. nigerrimus also contains two N-protocatechuyl-L-phenylalaninol derivatives, nigerrimin A and B, the first reported occurrence of such compounds in nature. Their configuration was established by the synthesis of nigerrimin B
