Stereoselective synthesis of (Z)-ketene selenothioacetales via hydrozirconation of lithium alkynylselenolate anions
Zhong, Ping,Huang, Nan-Ping
, p. 2423 - 2428 (2007/10/03)
Lithium alkynylselenolate anions react completely with 1.0 equiv of Cp2Zr(H)Cl in THF at room temperature to give exclusively the α-zirconated vinylselenolate intermediates 3, which by treatment with alkyl halide afforded the α-zirconated vinyl alkylselenides intermediates 4. Reaction of 4 with alkyl sulfenyl chlorides results in the formation of (Z)-ketene selenothioacetales 5 with total control of the regio- and stereochemistry.
Stereoselective synthesis of (Z)-ketene selenothioacetals via hydrozirconation of alkylacetylenic selenides
Zhong,Guo
, p. 370 - 371 (2007/10/03)
Hydrozirconation of internal acetylenic selenides afforded (E)-α-zirconated vinylic selenide intermediates, which react with alkylsulfenyl chlorides to give (Z)-ketene slenothioacetals in good uield.
Syntheses of Ketene Thioselenoacetals and of γ-Unsaturated Se-Alkyl Carboxylic Thionoselenoesters
Lemarie, Margareth,Vallee, Yannick,Worrell, Mark
, p. 6131 - 6134 (2007/10/02)
The alkylation of Se-alkyl carboxylic thionoselenoesters enethiolates stereoselectively leads to ketene thioselenoacetals.When the alkylation is conducted with an allylic halide a thio-Claisen rearrangement is observed.
