Expedient Synthesis of Highly Functionalised Cyclic Imines
摘要:
Aryl- and heteroaryl fused cyclic imines are obtained from the starting acetal via a directed metallation-alkylation-condensation sequence using cyclic sulfamidates as the electrophile. A variety of aromatics and heteroaromatics are demonstrated to be applicable to this methodology, which produces highly versatile cyclic imine building blocks for drug discovery and total synthesis programmes.
