The reaction of 1-lithiuo (phenylsulfinyl)cyclopropane with various electrophiles was studied.The reductive deoxygenation of the resulting adducts with TiCl4/Zn provided 1-substituted (phenylsulfinyl)cyclopropanes.

Several esters of norethisterone (17α-ethynyl-17β-hydroxyestr-4-en-3-one) with carboxylic acids containing a cyclopropyl or cyclobutyl ring have been synthesized and the stereochemistries of the side-chains determined.

The reactions of a variety of 1,3-bis(phenylthio)propanes with butyllithium have been shown to produce cyclopropyl phenyl sulfides in good to high yields.A new and convenient in situ preparation of 1-lithiocyclopropyl phenyl sulfide can be readily carried out by treating 1,3-bis(phenylthio)propane with 2 equiv. of butyllithium at 0 degC in THF.The reaction with electrophiles proceeds in good yield.O-Aryl and O-alkyl S-cyclopropyl dithiocarbonates also can be prepared in good yields. 1,2-Bis(phenylthio)ethane was converted to phenyl vinyl sulfide on treatment with butyllithium, while 1,4-bis(phenylthio)butane was recovered unchanged by a similar treatment.

1,3-Bis(phenylthio)propane reacted readily with 2-2.2 equiv. of n-butyllithium in THF at 0 degC to afford 1-lithiocyclopropyl phenyl sulfide.Treatment of the substituted 1,3-bis(phenylthio)propanes with 1.1 equiv. of n-butyllithium afforded the correspond
