A novel tin-free procedure for alkyl radical reactions

Desulfuration as a source of alkyl radicals: The addition of alkylsulfanyl radicals to isocyanides gives the corresponding alkyl radicals. This methodology can replace the usual tin-mediated radical procedures and allows for the generation of tertiary, secondary, and even nonstabilized primary radicals that can be used efficiently in reductive defunctionalizations and intermolecular additions to electron-rich olefins (see scheme).

Method for separating contaminants from 3-(2′-Acetoxy-Ethyl-Dihydro-2(3H)-Furanone

A process for removing impurities from 3-(2′-acetoxyethyl)-dihydro-2(3H)-furanone (I), which comprises initially preparing the 3-(2′-acetoxyethyl)-dihydro-2(3H)-furanone containing the undesirable impurities in a manner known per se by acetylating 3-(2′-hydroxylethyl)-dihydro-2(3H)-furanone, subsequently treating it with strong mineral acids and finally removing the decomposition products of the undesirable impurities from I.

Preparation of alpha-substituted upsilon-butyrolactones

γ-butyrolactones of the general formula I STR1 where R1 is hydrogen or alkyl of 1 to 4 carbon atoms which may be substituted by lower alkoxy or acyloxy and R2 is hydrogen or straight-chain or branched alkyl which is unsubstituted or substituted by a functional group or is aryl, are prepared by reacting an alkylene oxide of the general formula II STR2 with an acylacetate of the general formla III STR3 where R1 and R2 have the above meanings and R3 and R4 are each alkyl of 1 to 6 carbon atoms or aryl, and R4 may furthermore be hydrogen, in the presence of a catalyst at elevated temperatures, by a process in which the reaction is carried out in the presence of an alkali metal halide, of an ammonium halide, preferably a quaternary ammonium halide, of a phosphonium halide, of an alkali metal phosphate or of an alkali metal carbonate at from 20° to 200° C. and under from 1 to 50 bar.
