  The first total synthesis of roquefortine D

  摘要：

  The synthesis of roquefortine D (1), an alkaloid isolated from the cultures of Penicillium roqueforti, is described. The absolute stereochemistry of the natural product was determined by comparison of its optical rotation with that of the synthetic product. A photo-cleavable o-nitrobenzyl group was utilized for histidine side chain protection, and the cyclisation to the diketopiperazine was carried out under mild conditions.
