Sulfinimidate Esters as an Electrophilic Sulfinimidoyl Motif Source: Synthesis of N-Protected Sulfilimines from Grignard Reagents

In this work we investigated, for the first time, the reactivity of sulfinimidate esters as an electrophilic sulfinimidoyl motif source. The reaction of such sulfinimidate esters with Grignard reagents enables the preparation of protected sulfilimines in high yields and with a remarkable structural variability. Moreover, the transformation can be performed in CPME (cyclopentyl methyl ether) as a green solvent under environmentally responsible conditions.

Automated summary

The reactivity of sulfinimidate esters as electrophilic sulfinimidoyl motif source and their reaction with Grignard reagents for preparation of protected sulfilimines were investigated for the first time in this work. Results showed high yields, remarkable structural variability, and environmentally responsible conditions using CPME as a green solvent for this transformation.
