Highly regioselective 1,2-addition of alkoxybenzyl Grignard reagents to α-oxoketene dithioacetals: A facile regiocontrolled synthesis of alkoxynaphthalenes and their condensed analogs via aromatic annelation
Mehta, Barun K.,Nandi, Sukumar,Ila,Junjappa
, p. 12843 - 12852 (1999)
4-Methoxybenzyl- (A), 3,4-dimethoxybenzyl- (B) and 3,4- methylenedioxybenzyl- (C) Grignard reagents are shown to undergo regioselective 1,2-addition with various acyclic and cyclic α-oxoketene dithioacetals to afford carbinol dithioacetals which on BFsub
Unexpected hydrobromic acid-catalyzed C-C bond-forming reactions and facile synthesis of coumarins and benzofurans based on ketene dithioacetals

experimental part, p. 13450 - 13457 (2011/02/27)
Hydrobromic acid was found to be a unique catalyst in C-C bond-forming reactions with ketene dithioacetals. Distinctly different from other acids (including Lewis and Bronsted acids), the remarkable catalytic performance of hydrobromic acid in catalytic a
Chemoselective conjugate 1,4-reduction of α-oxoketene dithioacetals with zinc in acetic acid: Synthesis of β-oxodithioacetals
Rao, Ch. Srinivasa,Patro, Balaram,Ila, Hiriyakkanavar,Junjappa, Hiriyakkanavar
, p. 57 - 59 (2007/10/03)
Acyl ketene dithioacetals 1 and 3 undergo highly chemoselective conjugate 1,4-reduction with zinc in acetic acid to give β-oxodithioacetals 2 and 4 in high yields.
Oxidative Generation of Thioalkyl Cations from 2-Tributylstannyl-1,3-dithianes and 1-(Tributylstannyl)alkyl Sulfides and Their Reactions with Olefinic Nucleophiles

, p. 2995 - 3003 (2007/10/02)
2-Tributylstannyl-1,3-dithianes and 1-(tributylstannyl)alkyl sulfides are oxidized with ammonium hexanitratocerate(IV) or ferrocenium hexafluorophosphate to generate their cation radicals, which dissociate into the carbocations and tributylstannyl radical
Regio- and chemoselective conjugate 1,4-reduction of α-oxoketene dithioacetals with sodium borohydride and sodium cyanoborohydride
Srinivasa Rao,Chakrasali,Ila, Hiriyakkanavar,Junjappa, Hiriyakkanavar
, p. 2195 - 2204 (2007/10/02)
Theα-oxoketene dithioacetals 1 are shown to undergo conjugate 1,4-reduction in highly regio- and chemoselective manner with sodium borohydride in acetic acid to afford the corresponding β-oxodithioacetals 5 in good yields. These results have been rational
