Weissenfels, Manfred,Pulst, Manfred,Greif, Dieter
, p. 17 - 30 (2007/10/02)
2H-Thiopyranes with a side chain in position 2 of the ring and a terminal formyl group are resonance stabilized compounds.They represent solid, coloured substances, both thermal stable and also reactive, especially against several nucleophilic reagents.Th

Dimethyl-2-chloro-propene-1,3-dicarboxylate is a easily available reactive C2-building block for the synthesis of 2H-thiopyran derivatives 1a-n in good yields via -cyclisation reactions using β-thioxoaldehydes and their derivatives as C3S-synthons
