从拟阿氏菌属分离的生物活性化合物(2 RS,8 R,10 R)-YM-193221(1)和酪酪蛋白(2)的分步合成,由L-酪氨酸经六步和八步完成。天然YM-193221的相对立体化学被确定为8 R *,10 R *。
Short-step syntheses of (2RS,8R,10R)-YM-193221 (1) and tyroscherin (2), which are biologically active compounds isolated from Pseudallescheria sp., were accomplished in six and eight steps from L-tyrosine. The relative stereochemistry of natural YM-193221 was determined to be 8R *,10R *.
