Tricholomines A and B, two new amides from the fruiting bodies of Tricholoma bakamatsutake

Two new amides tricholomines A (1) and B (2), along with nine known compounds, were isolated from the dried fruiting bodies of Tricholoma bakamatsutake. Their structures were determined on the basis of extensive spectroscopic analysis or comparison with the data in the literatures. The absolute configuration of 1 was confirmed by single crystal X‐ray diffraction analysis.
