A synthesis of 1--acetyl-3--(4-methoxybenzyl)-4--(9-fluorenylmethoxycarbonyl)-4--methyl-L-pyrrolosamine (), which constitutes a protected form of the ,-dimethyl-L-pyrrolosamine residues found within the antiproliferative bacterial metabolites (-)-lomaiviticins A and B ( and , respectively), is reported. The synthetic route to proceeds in eight steps and 13% overall yield from ()-crotyl alcohol. The protected carbohydrate is envisioned to be a useful derivative for syntheses of and .
据报道,合成了1-乙酰基-3-(4-甲氧基苄基)-4-(9-芴甲氧羰基)-4-甲基-L-吡咯胺(),它是抗增殖细菌代谢产物(-)-洛马维菌素A和B(分别为和)中发现的α,α-二甲基-L-吡咯胺残基的一种保护形式。从()-巴豆醇出发,通过八步反应合成,总收率为13%。受保护的碳水化合物被认为是合成和的有用衍生物。
