Abstract:
Described are methods for preparing phenols, benzene carboxylic acids, esters and anhydrides thereof from furanic compounds by reaction with a dienophile, wherein the furanic compounds are reacted with a hydrazine and/or oxime and then reacted with a dienophile.

Claim (Index 1):
A method of preparing a compound having a backbone comprising formula (I): wherein:\n G is OH, CHO, CO 2 H, an ether, an ester, or an anhydride of a biomass-derived compound, \n the method comprising:\n (i) reacting a biomass-derived compound having a backbone comprising formula (II) with a compound of formula (III): \n wherein:\n X is O and z is 0, or \n X is N and z is 1, \n R 1  is hydrocarbyl group, a heteroatom containing hydrocarbyl group, or a link to a heterogeneous support, and \n R 2  is hydrogen, a hydrocarbyl group, a heteroatom containing hydrocarbyl group, or a link to a heterogeneous support, \n to give a compound with having a backbone structurc according to comprising formula (IV): (ii) reacting the compound having a backbone comprising formula (IV) with a dienophile to give a compound having a backbone comprising formula (V): (iii-a) hydrolyzing said compound having the backbone comprising formula (V) to yield the compound having the backbone comprising formula (I), wherein G is CHO, or (iii-b) optionally decarbonylating the product of step (iii-a) to provide the compound having the backbone comprising formula (I), wherein G is OH, or (iii-c) optionally oxidizing the product of step (ii), (iii-a), or a combination thereof to yield the compound having the backbone of formula (I), wherein G is CO 2 H, or (iii-d) converting the compound having the backbone comprising formula (I), wherein G is OH, CHO, or CO 2 H to the ether, ester, or anhydride thereof.
