THE SYNTHESIS OF CYCLODECANE DERIVATIVES BY INTRAMOLECULAR ALKYLATION OF AN α-PHENYLSULFENYL KETONE
Caine, Drury,Stanhope, Bruce
, p. 33 - 44 (1992)
The acyclic ω-tosyloxy-α-phenylsulfenyl ketone 1a, derived from R-(-)-carvone, underwent intramolecular alkylation to give the cyclodecenone derivative 2a in good yield. Oxidation of the sulfide to the sulfoxide and thermal elimination of phenylsulfinic a
