A suitably positioned (1,2-, 1,4-, and 1,5-) intramolecular sulfide interferes with the iodotrimethylsilane-promoted iodine for hydroxyl substitution, as well as the related alcohol deprotection procedure (regioselective cleavage of methyl ethers). The ou
Stereochemistry of methylation of cyclic sulfonium ylides
Garbesi, Anna
, p. 547 - 550 (2007/10/02)
Low temperature methylation of 6-membered sulfonium ylides is highly stereoselective and configurational inversion has been established in at least one case. No appreciable stereoselectivity has been observed in 5-membered ylides.
