HETEROCYCLES FROM YLIDES.PART IX.A CONVENIENT SYNTHESIS OF l-SULFONYL-2,3-DISUBSTITUTED 2,3-DIHYDROINDOLES

摘要

The reaction of sulfur ylides (1) with N-(2-bromomethyl-phenyl)benzenesulfonamides (4) gives 2,3-dihydroindoles (5) whose structure and stereochemistry were assigned on the basis of analytical and spectroscopic data.Some chemical transformations of 5 are reported.
