Abstract:
Provided herein are methods of producing halomethylfuroic and acyloxymethylfuroic acid and ester compounds from furfural starting compounds. For example, 5-chloromethyl-2-furoic acid may be produced from 5-chloromethylfurfural, in the presence of various oxidants. Salts of the furoic acids may also be produced.

Claim (Index 1):
A method of producing a compound of formula (II), or a salt thereof, comprising combining a compound of formula (I) with an oxidant to produce the compound of formula (II), or a salt thereof, wherein:\n the compound of formula (I) is:  is a double bond or a single bond; j is 2 when   is a double bond, or j is 6 when   is a single bond; each R n  is independently H or alkyl; R x  is halo, OC(O)R a  or OR b ;\n wherein R a  is H, aliphatic or aromatic, and R b  is aliphatic; and \n the compound of formula (II) is: wherein R x , j and   are as defined for formula (I); and Rz is H or aliphatic; and the oxidant is:\n (i) a compound of formula W b -O 2 X b , wherein W b  is a Group I cation and X b  is halo; \n (ii) W d -O 3 X d , wherein W d  is a Group I cation and X d  is halo; \n (iii) HX b O 2 , wherein X b  is halo; \n (iv) HX d O 3 , wherein X d  is halo; or \n (v) X c O 2 , wherein X c  is halo.
