Pyrroloisoquinoline-based peptidomimetics are of significant interest in bioorganic chemistry as these targets are known to exhibit type II′ β-turn activity. In this paper we present a novel approach to such pyrroloisoquinoline templates based on a stereoselective N-acyliminium-mediated cyclization reaction to construct the heterocyclic core, coupled with an enolate amination protocol. We have applied

In this paper we report a facile and stereoselective approach to the pyrroloisoquinoline ring system through the application of N-acyliminium chemistry from readily available non-racemic chiral templates. The stereochemical outcome of the cyclisation reactions has been determined by NOE and X-ray crystallography. We also demonstrate the synthetic potential of our new approach through removal of the pendant hydroxymethyl auxiliary from a product of cyclisation.
在本文中,我们报告了通过应用 N-酰亚胺化学,从容易获得的非外消旋手性模板出发,对吡咯异喹啉环系统进行简便和立体选择性研究的方法。环化反应的立体化学结果是通过 NOE 和 X 射线晶体学确定的。我们还通过去除环化反应产物中的羟甲基助剂,证明了新方法的合成潜力。
