The rearrangements of α-imino-thioaldehydes into dihydro-1,3-thiazoles

α-Imino-thioaldehydes were generated by retro-Diels-Alder reaction under nash vacuum thermolysis conditions. They were found to be unstable and cyclized to 2,3-dihydro-1.3-thiazoles. This cyclization was investigated by ab initio calculations.

NEW REACTIONS WITH THIOALDEHYDES AND THIENIUM CATIONS

i) When generated under FVT conditions α-imino-thioaldehydes undergo a cyclization to dihydro-1,3-thiazoles. ii) Thienium cations, generated during a Pummerer reaction, can be trapped with dienes.
