Diels-Alder reaction of methoxythiophenes: A new one-pot synthesis of dimethyl phthalates

A series of dimethyl phthalates have been prepared from methoxythiophenes and dimethyl acetylenedicarboxylate (DMAD) in xylene. When the reaction is carried out in acetic acid, thienylfumarates are obtained.

Evaluation of some preparations of trialkoxyphthalic acid derivatives

Several approaches to trialkoxyphthalic acid derivatives, potential intermediates in a fredericamycin synthesis, were tested. Sequences based on a Diels-Alder/retro Diels-Alder reaction, a cyanide addition to a quinone, an Elbe oxidation, and an amide-directed ortho-lithiation are discussed in terms of length, yields, convenience, and the versatility of the product of each.
