Lysine is proposed as an alternative biosynthetic precursor of the pyrrole-imidazole alkaloids frequently found in marine sponges. As a putative key intermediate, the natural product Nalpha-(4-bromopyrrolyl-2-carbonyl)-L-homoarginine (1) from the sponge Agelas wiedenmayeri was synthesized in the solid phase starting from Fmoc/Pmc-protected L-homoarginine and in solution starting from readily available
赖氨酸被提议作为常见于海洋海绵中的吡咯-咪唑生物碱的另一种生物合成前体。作为推定的关键中间体,从Agelas wiedenmayeri海绵中得到的天然产物Nalpha-(4-溴吡咯烷基-2-羰基)-L-高精氨酸(1)在固相中由Fmoc / Pmc保护的L-高精氨酸合成,并在溶液从容易获得的L-赖氨酸甲酯开始。
