2-Methyl-4 -phenylthio

The addition of the lithium enolates of various acetic add esters to (S)-3-(4-methylphcnyl-sulfmyl)-2(5//)-liiranone and (,S)-5,6-dihydro-3-(4-methylphenylsulfinyl)-2//-pyran-2-one gives, after desulfurization with Raney nickel, 4-substituted dihydro-2(3//)-furanoncs and 4-substituted tetrahydro-2//-pyran-2-ones, respectively, in good to quantitative enantiomeric excess. Addition of the enolate occurs via the nonchelate mode. The enolate of methyl (phenylthio)acetatc is best overall in regards to chemical yields and enantiomeric purity of the final lactone product13. [Pg.1049]
