Alkylation and cyclopentannulation of phospholene derivatives
Pakulski, Zbigniew,Kwiatosz, Renata,Micha? Pietrusiewicz
, p. 1481 - 1492 (2007/10/03)
The deprotonation of 1-phenyl-3-phospholene 1-oxide, 1-sulfide or 1-borane with 1 or 2 equiv of LDA, followed by quenching with electrophiles gave a range of 2-mono- or 2,5-disubstituted phospholene derivatives in good yield. Only trans substitution in re
Chiral base promoted enantioselective rearrangement of organophosphorus epoxides
Pakulski, Zbigniew,Koprowski, Marek,Pietrusiewicz, K. Micha?
, p. 8219 - 8226 (2007/10/03)
Cinchona alkaloids serve as effective chiral bases for enantioselective rearrangement of 3,4-epoxyphospholane oxides resulting in the formation of P,C-chirogenic 4-hydroxy-2-phospholene derivatives with up to 52% ee. A stereochemical course of the epoxide
THE REACTIONS OF Δ3-PHOSPHOLENES WITH SULPHENATE ESTERS AND SULPHENAMIDES
Hammond, Philip J.,Lloyd, John R.,Hall, C. Dennis
, p. 67 - 80 (2007/10/02)
The reactions of 1-methyl and 1-phenyl-Δ3-phospholenes with sulphenate esters give rise to a range of products involving rearrangement of the endocyclic double bond, dealkylation to phospholene oxides and fragmentation of the ring.When reacted with N,N-diethyl methylsulphenamide, the same phospholenes give ylids by loss of a proton from position-2 or 5 of an intermediate phospholenium amide.
