Diastereoselective synthesis of cyclopentene spiro-rhodanines containing three contiguous stereocenters via phosphine-catalyzed [3 + 2] cycloaddition or one-pot sequential [3 + 2]/[3 + 2] cycloaddition

Two different diastereoselective phosphine-catalyzed cascade reactions to form cyclopentene spiro-rhodanine scaffolds are described. In the first approach, alkynoate derivatives and 5-arylidene-3-( tert -butyl)-2-thioxothiazolidin-4-one react in the presence of PBu 3 through a [3 + 2] cycloaddition...
