<scp>Ming‐Phos</scp>/Gold(I)‐Catalyzed Stereodivergent Synthesis of Highly Substituted Furo[3,4‐<i>d</i>][1,2]oxazines^†

Abstract

Summary of main observation and conclusion A gold(I)‐catalyzed asymmetric intermolecular tandem [3+3]‐cyclization reaction of 2‐(1‐alkynyl)‐2‐ alken‐1‐ones with nitrones has been developed by using Ming‐Phos as a chiral ligand. This method enables access to the stereodivergent synthesis of highly substituted furo[3,4‐ d ][1,2]oxazines in excellent efficiency and stereoselectivity (up to 99% yield, 99% ee , &gt;20 : 1 dr).
