, p. 481 - 482 (2007/10/03)
Vinyl and allylic nitroalkenes have been converted into the corresponding carbonyl compounds in good yield using tin(II) chloride dihydrate under microwave irradiation.
Synthesis of Cholestenothiazoles and Cholestanooxazolidine
Ahmad, M. S.,Alam, Zafar
, p. 486 - 488 (2007/10/02)
4β,5-Epoxy-5β-cholestan-3-one (I) reacts with thiourea to afford 5β-hydroxycholest-3-eno-2'-aminothiazole (II) while with thiacetamide it furnishes 3,5-cholestadieno-2'-methylthiazole (III) and 5β-hydroxycholest-3-eno-2'-methylthiazole (IV). 6β-Chloro-5-hydroxy-5α-cholestane (V) on treatment with KSCN in dimethylformamide gives cholesta-4,6-diene (VI), 5α-chloestan-6-one (VII), 5-hydroxy-5α-cholestan-6α-yl isothiocyanate (VIII), 5-hydroxy-5α-cholestan-6-one (IX) and 5α-cholestano-2'-thiooxooxazolidine (X).The structures of these compounds have been established on the basis of spectral properties, analytical data and also by direct comparison with authentic samples where available.
