Muramatsu, Wataru,Nakano, Kimihiro
, p. 437 - 440 (2015)
We have developed a one-step method for introducing aryl, alkyl, and amide groups at the C(1)-position of isothiochromans via an oxidation reaction using hypervalent iodine(III), [bis(trifluoroacetoxy)iodo]benzene (PIFA), followed by an nucleophilic addition reaction using Grignard reagents and an amide.
Ring Expansion of Cyclic α-Ethynyl Sulfonium Ylides by -Sigmatropic Rearrangement: Formation of Thiocin, Thionin, and Thiecin Derivatives
Sashida, Haruki,Tsuchiya, Takashi
, p. 3644 - 3652 (2007/10/02)
The cyclic 1-ethoxycarbonylmethyl-2-ethynyl sulfonium salts (15Aa-d, 15Ba-d, and 15Ca-d),prepared from thiolane (12A), thiane (12B), and thiepane (12C), were treated with 1,5-diazabicycloundec-5-ene (DBU) to result in ring expansion, giving thiocin
