The first de novo synthetic pathway to the exceptionally rare C5-nor stemmadenine natural product, conolidine, and the first asymmetric synthesis of any member of this natural product class arc described. C5-nor stemmadenine compositions are also described. These compounds, for example,(+/- )-,(+)- and (-)-conolidine are potent and efficacious non-opioid analgesics in tonic and persistent pain.
第一种全新的合成途径,用于制备极为罕见的C5-去甲基史丹马
丁醇天然产物conolidine,以及该
天然产物类别中任何成员的第一种不对称合成方法。同时描述了C5-去甲基史丹马
丁醇的组成。这些化合物,例如(+/-)-,(+)-和(-)-conolidine,在持续性疼痛中是有效的非阿片类镇痛剂。
