Introduction of alkyl- or phenylseleno group by the ring opening of cyclic ethers using dialkyl- or alkylphenylselenium dibromide and sodium borohydride
Takanohashi,Funakoshi,Akabori
, p. 2733 - 2741 (2007/10/02)
The reaction of dialkyl- or alkylphenylselenium dibromide with cyclic ethers in the presence of sodium borohydride gave ω-hydroxyalkyl alkyl or phenyl selenides as the ring opening products of the cyclic ethers.
Intramolecular SH2 macrocyclisations
Baldwin, Jack E.,Adlington, Robert M.,Mitchell, Mark B.,Robertson, Jeremy
, p. 5901 - 5918 (2007/10/02)
The synthesis of 10-15 membered α-methylene macrocyclic lactones from the functionalised allylstannanes (7e)-(7j) is described. Attempts to synthesise analogous 6-9 membered lactones proved unsuccessful, resulting instead in the production of dilactones and AIBN derived adducts.
Radical Reactions in Synthesis: Intramolecular SH2' Macrocyclisations
Baldwin, Jack E.,Adlington, Robert M.,Mitchell, Mark B.,Robertson, Jeremy
, p. 1574 - 1575 (2007/10/02)
The synthesis of 10-15 membered α-methylene lactones 1 from the functionalised allyl stannanes 2 occurs cleanly in moderate to high yield under free radical conditions via an intramolecular SH2' reaction.
THE C-O BOND CLEAVAGE OF CYCLIC ETHERS WITH TRIS(PHENYLSELENO)BORANE-LEWIS ACID
Kataoka, Tadashi,Yoshimatsu, Mitsuhiro,Shimizu, Hiroshi,Kawase, Yoshitaka,Hori, Mikio
, p. 889 - 893 (2007/10/02)
Tris(phenylseleno)borane (1) has a hard boron element and a soft selenium element, and therefore it was expected that 1 cleaves the C-O bond.Tetrahydrofuran and tetrahydropyran were cleaved with 1 in the presence of zinc iodide to produce the δ- and ε-phe
