The scope for a range of sp2-sp2 coupling protocols to elaborate the phenyl-indole, indole-oxazole, oxazole-oxazole, and quaternary carbon units in the marine natural product diazonamide A 1 are described, leading to the synthesis of the benzofuran oxazoles 11a and 18, the benzofuran/biphenyl/indole 16, and the indole-bis-oxazole, 25.
描述了一系列sp 2 -sp 2偶联方案的范围,该方案可详细阐述海洋天然产物重氮酰胺A 1中的苯基-吲哚,吲哚-恶唑,恶唑-恶唑和季碳单元,从而导致苯并呋喃的合成恶唑11a和18,苯并呋喃/联苯/吲哚16和吲哚-双-恶唑25。
