this paper, we report a new process for the construction of 3,4,5-substituted isothiazoles via reaction cascades including Pummerer-like rearrangement, nucleophilic condensation, and sulfenamide cyclization followed by concomitant elimination and dehydration under mild reaction conditions. This process provides isothiazoles bearing fluorine and other functional groups in good to excellent yields from

Highly stereoselectivesyntheses of chiral indolines and tetrahydroquinolines are achieved by combining the asymmetric Zn-mediated allylation of chiral N-tert-butanesulfinyl imines with efficient intramolecular C–N cross-coupling. Herein, the advantages of such a synthetic strategy are illustrated by the synthesis of indolines and tetrahydroquinolines with quaternary stereocenters and multi-substituted
Herein, we report a new process for the synthesis of highlyfunctionalizedpyridines based on a tandem Pummerer-type rearrangement, aza-Prins cyclization, and elimination-induced aromatization. This formal [5+1] cyclization provides pyridines in good yields with easily accessible starting materials. The synthetic potential of our new method is further demonstrated in the modification of the frameworks

Direct reaction of isocyanides with some sulfenic-acid-generating sulfoxides led to the effective formation of the corresponding thiocarbamic acid S-esters in good to high yields. A multicomponent reaction involving isocyanide, sulfoxide, and a suitable nucleophile has also been developed, providing ready access to a diverse range of sulfur-containing compounds, including isothioureas, carbonimidothioic
