For preparation of 5-monosubstituted or 5,5-disubstituted 2,4-dienals, 1-(methylthio)-5-(p-tolylsulfonyl)-1,3-pentadiene (4) is revealed to be an important precursor.When 5-(methylthio)-5-(p-tolylsulfonyl)-1,3-pentadiene, that is easily obtainable from (methylthio)methyl p-tolyl sulfone, was treated with silica gel, 1,5-rearrangement of p-tolylsulfonyl group occurred to give 4.The conditions for mono- or dialkylation of 4 followed by hydrolysis leading to the dienals are desribed.
Application of the Peterson Olefination to the Preparation of Substituted Triafulvenes from Methoxycyclopropenylium Triflates
Schubert, Hans H.,Stang, Peter J.
, p. 5087 - 5090 (2007/10/02)
Three new unusually substituted triafulvenes were prepared by reacting methoxycyclopropenylium triflates with α-silyl substituted anions.The mode of a nucleophilic attack varied, depending on the anion.Attack occurred at the methoxy substituted carbon, yi
