Ketene S,S-acetal 2 reacts with aminoethanol to afford 2-(1-aceta1-2-oxo propylidine)oxazolidine 3 which was allowed to react with some active methylene compounds having an α- cyano or α-keto group to give spiro(pyran -4,2'-oxazolidine) derivatives 5-11.
Synthesis of Acetyl-Substituted Heterocyclic Ketene Aminals and Their Deactylation Reaction
Wang, He-Ting,Wang, Xiao-Jun,Huang, Zhi-Tang
, p. 2141 - 2145 (2007/10/02)
The acetyl-substituted heterocyclic ketene aminals 3-6 were synthesized by the reaction of ketene dithioacetals 2 with diamines.The deacetylation of heterocyclic diacetyl ketene-aminals by alkali was studied, and the corresponding monoacetyl derivatives were studied.
Synthesis of Heterocyclic Ketene N,O-Acetals and Their Reactions with α,β-Unsaturated Esters
Huang, Zhi-Tang,Zhang, Ping-Cheng
, p. 2011 - 2016 (2007/10/02)
Ketene dithioacetals 2 react with 2-aminoethanol or 1-amino-2-propanol to afford the corresponding substituted 2-methyleneoxazolidines 3 and 4.In some cases, 3 and 4 react with α,β-unsaturated esters to give 5H-oxazolopyridine derivatives 5 by an e
