We report herein a protocol for thiolactam preparation with potassium sulfide via visible-light-mediated C(sp3)–H thiocarbonylation, in which polysulfide dianions and radical anions generated from potassium sulfide were the key active species. A variety of thiolactams were straightforward established under mild conditions. Moreover, it was successfully applied to structural modification of tetrahydroberberine.

Nonstabilized azomethine ylides generated from the various β-amino alcohols N-oxides 13, 17, 23 and 24 undergo cycloaddition reactions with unactivated alkenes to afford the corresponding pyrrolidines 14a-g, 18a-g, 25 und 27 in moderate to good yields.These compounds are precursors of NH pyrrolidines substituted in position 2, 3 or 4.
A 3+2 CYCLOADDITION ROUTE TO N-H PYRROLIDINES DEVOID OF ELECTRON-WITHDRAWING GROUPS

N-H pyrrolidines are obtained from intermolecular 3+2 cycloaddition reactions between nonactivated olefins and ylide generated from amine N-oxide 1 structurally designed in such a way as to allow easy dealkylation of the cycloadduct.
