The cause of this disagreement was soon discovered. I n a new study of neolactose, Richtmyer and Hudsonl6 improved the method of preparing acetochloroneolactose; a 3 5 4 0 % yield of th e recrystallized material was obtained consistently by heating each 50 g.

INTRODUCTION It was in 1910 that Levene and Jacobs’ first applied the classical cyanohydrin synthesis* to D-ribose (I), a five carbon atom aldehyde sugar (aldopentose) which had become more readily available through their earlier research on nucleic acids. Two new aldohexoses were thus obtained in sirupy form, and characterized by suitable crystalline derivatives.

5) in chloroform, recrystallization from 125 parts of 95% alcohol. The melting point of the latter substance agrees with Philippe's valueM; the rotation is the first record. The heptabenzoate of the meso alcohol is a new substance. Pure allitol (meso configuration; m. p. 15S151") was described for the first time by Lespieau and Wiemann,"S who synthesized it by the hydroxylation of one of the stereoisomaric forms of divinylglycol. Its structure was established rigorously by Steiger and Reichstein"' when they demonstrated its identity with tbe product obtained by the reduction of D-allose.
