Nambiar, Krishnan P.,Mitra, Abhijit
, p. 3033 - 3036 (1994)
A mild method for selective cleavage of tetrahydropyranyl ethers in the presence of other acid sensitive functionalities such as acetonides, methoxymethyl ethers, methylenedioxy ethers, mesitylaldehyde acetals and t-butyldimethylsilyl ethers using Lewis acid-thiol system is described.
A concise stereocontrolled formal total synthesis of (+/-)-podophyllotoxin using sulfoxide chemistry.
Casey, Mike,Keaveney, Claire M
, p. 184 - 185 (2007/10/03)
A short stereoselective formal total synthesis of (+/-)-podophyllotoxin has been carried out from a sulfoxide, using a one-pot tandem conjugate addition/aldol/electrophilic aromatic substitution reaction to form a tetralin, which was converted into picrop

The 2-benzopyran-3-one 10 is a stable, isolable and useful Diels-Alder diene; its methyl 4-benzoyloxycrotonate adduct 23 formed regioselectively and stereoselectively in acetonitrile is reduced with H2/Pd to give 31 with inversion of C-1 stereochemistry.T
