Abstract

Procedure for the preparation of 2,3,4,6-substituted 2-keto-I-gulonic acid derivatives of the general formula ** (See formula) ** in which when n is 1, R'is sodium; potassium, ammonium, ammonium substituted by one or more lower alkyl or lower alkenyl, hydroxy-lower alkyl, straight or branched chain aliphatic hydrocarbyl; halo-lower alkyl; and, when n is 2, R'is calcium, magnesium or lower alkylene, R'1, R'2, R'3 and R'4 are lower alkyl, n is an integer from 1 to 2 and X is a number from 0 to 1, enantiomers and racemic mixtures, except that when R'is methyl, sodium or potassium, R'1, R'2, R'3 and R'4 are lower alkyl with more than one carbon atom, whose procedure comprises reacting an acid of the general formula ** (See formula) ** in which R'1, R'2, R'3 and R'4 have the meaning indicated in formula XX above, with a compound of the general formula X-R5 VI in which X is chlorine, bromine or a p-tolylsulfonyl ester and R5 is straight or branched chain aliphatic hydrocarbyl or halo-lower alkyl; in the presence of a base.
