G. Capozzi et al., FORMATION AND HETERO-DIELS-ALDER REACTION OF ALPHA-IMINOSULFINES - SYNTHESIS OF 5,6-DIHYDRO-1,4-THIAZINE S-OXIDES, Synthesis, (6), 1998, pp. 915-918
Simple transformations of anthracene derived cycloadduct 1 allows the
in situ generation of alpha-iminosulfines (alpha-imino thioketone S-ox
ides), a new class of sulfur-nitrogen substituted electron-poor dienes
useful for the synthesis of the 1,4-thiazine S-oxide ring system.
