Ikemi, Yukio
, p. 1597 - 1600 (2007/10/02)
Diphenycyclopropenethione undergoes nucleophile attack by pyridinium disubstituted ylides 1a-1e to produce the corresponding 2-pyranthione 3a, 2-pyrone 4a or 4c, thiopyran-2-one 6a, 6b, 6d or 6e, and/or 5H-thienothiopyran 5a.
REACTION OF PYRIDINIUM DISUBSTITUTED METHYLIDES WITH DIPHENYLCYCLOPROPENETHIONE
Matsumoto, Kiyoshi,Ikemi, Yukio
, p. 1445 - 1448 (2007/10/02)
Diphenylcyclopropenethione undergoes nucleophilic attack by pyridinium disubstituted ylides (1a-e) to produce the corresponding indeno-2-thiopyrone (3), 2-pyrone (5 or 10), 1-thio-2-pyrone (6, 8, 11 or 12), and/or 2-thiopyrone (4) derivatives.
