Versatile Spirocyclic Glycine‐Based Nitrones and Their Highly Stereoselective 1,3‐Dipolar Cycloaddition
摘要:
A convenient and efficient method for the synthesis of novel spirocyclic nitrones prepared from glycine derivatives is reported. The 1,3-cycloaddition reactions of the nitrones with alkenes lead to novel isoxazolidines in high yields and with excellent regio- and stereoselectivity.
