This report describes an improved synthesis of enantiomerically pure (S)-2-[4-(Dimethylamino)phenyl]-2,3-dihydro-N-[2-hydroxy-3-[4-[2-(1-methylethoxy)-phenyl]-1-piperazinyl]propyl]-1,3-dioxo-1H-isoindole-5-carboxamide (RWJ 69442), a potent and selective αla-adrenergic receptor antagonist for the treatment of benign prostatic hyperplasia. The synthesis highlights less hazardous reagents, easier purification
该报告描述了对映体纯的(S)-2- [4-(二甲基氨基)苯基] -2,3-二氢-N- [2-羟基-3- [4- [2-(1-甲基乙氧基) -苯基] -1-哌嗪基〕丙基〕-1,3-二氧代-1- ħ -异吲哚-5-甲酰胺(RWJ 69442),一个有效的和选择性α拉-肾上腺素能受体拮抗剂用于治疗良性前列腺增生的治疗。该合成突出显示了较少的危险试剂,更易于纯化和更高的对映体纯度。所述Ñ苄基N-叔丁氧羰基胺6可以作为对映体纯的手性结构单元为不对称合成。
