With sodium borohydride in tetrahydrofuran/ethanol (5 : 1). the product ( I ) gives a 75 yield of a compound, m.p. 233 "C, that is identical with the recently prepared 2-(diphenylmethyl)imidaz0le[~1. When product ( I ) is boiled for 2 h in tetrahydrofuran/water (2: I ) it affords 2-(hydroxy-dipheny
The configuration of the alkylation products (e.g., 6 and 7) are fully in accord with this analysis. In summary, chiral auxiliary compounds (3) of a new shape have been described, and their action can be related to the stereoelectronics of enolate alkylations. The asymmetric environment of the auxi
Chlorination (at room temperature without solvent) of compound (2.) does not, like that of ethyl pentachloro-1,3butadienyl ether, cause ether fission with formation of an acid chloride [31, but instead leads to a-chloroethyl pentachloro-1,3-butadienyl sulfide (4) (84 %, b.p. 119 '(72.2 mm, n'," = 1.
