Yadav, Lal Dhar S.,Kapoor, Ritu
, p. 2344 - 2346 (2007/10/03)
Thiiranes are obtained in excellent yields and with high diastereoselectivity upon microwave irradiation of a mixture of α-haloketones, O,O-diethyl hydrogen phosphorodithioate and alumina-supported sodium borohydride in solvent-free conditions.
Stereoselective Synthesis of Unhindered Olefins by 2-Fold Extrusion Reactions
Collazo, Luis R.,Guziec, Frank S.
, p. 43 - 46 (2007/10/02)
Two-fold extrusion reactions of 1,3,4-thiadiazolines 1 provide a convenient stereoselective route to unhindered Z-olefins.An improved preparation of the thiadiazolines involves reaction of an aldehyde with H2S-hydrazine, followed by in situ oxidation of the intermediate predominantly trans thiadiazolidine 2.Stereospecific extrusion of nitrogen yields the cis-thiirane which upon treatment with triphenylphosphine affords the corresponding Z-alkene in good yields.
A NEW STRATEGY FOR THE STEREOSELECTIVE SYNTHESIS OF OLEFINS
Dybowski, Piotr,Skowronska, Aleksandra
, p. 4385 - 4388 (2007/10/02)
Highly stereoselective conversion of ketones into (Z)-olefins, via intermediate S-(β-oxoalkyl)thiophosphates and their seleno analogues is described.
Thiiranes: One-pot Synthesis from Alkenes, and Catalytic Desulphurization
Capozzi, Francesco,Capozzi, Giuseppe,Menichetti, Stefano
, p. 4177 - 4180 (2007/10/02)
The reaction of bis(trimethylsilyl)sulphide with bromine at -78 deg C forms trimethylsilylsulphenyl bromide which reacts with alkenes to give thiiranes.Trimethylsilyl bromide and iodide catalytically desulphurize thiiranes to alkenes.
