α-Phenylsulfinyl and α-Phenylsulfonyl radicals are generated by the reactions of α-chlorosulfoxides and α-chlorosulfones with tributyltin hydride, respectively. High reaction concentration (0.2 M) is required to ensure efficient generations of these radic
Applications of highly enantioenriched alcohols bearing a phenylthio group in the preparation of ring compounds. The two-pot synthesis of an enantiopure spiroacetal pheromone bearing three chiral centers

The new chiron (S)-6-phenylthio-2-hexanol (3) was prepared in high enantiomeric excess by baker's yeast reduction of the corresponding ketone. Enantioenriched alcohols 1, 2 and 3, prepared previously by a similar procedure, or their racemic counterparts, were transformed into ring closed compounds 5-methyl-2-(phenylthio)tetrahydrofuran (9), 6-methyl-2- (phenylthio)tetrahydropyran (10), 2-methyl-1-phenylsulfonyl cyclopropane (14), cyclobutane (15), cyclopentane (16), and a bee pheromone, (2S,6R,8S)- 2,8-dimethyl-1,7-dioxaspiro[5.5]undecane (20).
α-Sulfonyl radical initiated intramolecular tandem radical cyclization
Reutrakul,Poolsanong,Pohmakotr
, p. 6913 - 6916 (2007/10/02)
Suitable derivatives of hex-5-enyl α-sulfonyl radical undergo cyclization to produce complex cyclic systems by a multiple radical chain mechanism.
