- Preparation of α-Substituted S-Phenyl Thio Esters from Aldehydes and (Phenylthio)nitromethane
-
Acetaldehyde and isobutyraldehyde, RCHO, reacted with (phenylthio)nitromethane (KO-t-Bu, THF, t-BuOH) followed by methanesulfonyl chloride (Et3N, CH2Cl2) to give the (Z)-alkenes RCH=C(SPh)NO2.These reacted with the nucleophiles NuM = potassium phthalimid

- 1-Nitro-1-(phenylthio)propene as a New Nitro Olefin Reagent for 3-Methylfuran Annulation and Its Application to the Synthesis of Some Furanoterpenoids
-
1-Nitro-1-(phenylthio)propene (9) was synthesized from (phenylthio)acetic acid (6) in five steps.This nitro olefin reacted with dimedone (1) with KF catalysis to yield dihydrofurans 10a and 10b, both of which were converted to 3-methylfuran 13 on NaIO4 ox
