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 crystal and molecular structures of a pair of diastereomeric 2-diphenylthiophosphinoylcis-(4,6-dimethyl)-1,3-dithianes 2 have been determined by the X-ray method. The differences in corresponding bond distances in cis-2 and trans-2 are discussed in context of the anomeric effect operating in thi
The novel and versatile cyanomethyl 2amino-4-methylthiazolyl ketone (5) was prepared by treatment of bromomethyl 2-amino-4-methyl thiazolyl ketone (4) with potassium cyanide. Reaction of 5 with heterocyclic diazonium salts 6a,b and 10 afforded the corresponding hydrazones 7a,b and 11, respectively.
