Microwave-assisted solid-phase D?tz benzannulation reaction: A facile synthesis of 2,3-disubstituted-1,4-naphthoquinones

A microwave-assisted solid-supported D?tz benzannulation of chromium carbene complexes with various alkynes has been developed. The oxidative cleavage of the resulting resin-bound 1,4-naphthols affords 2,3-disubstituted-1, 4-naphthoquinone derivatives in good to moderate yields with high purities.

CONDENSATION INDOLE/NAPHTHOQUINONE. SYNTHESE D'UNE NOUVELLE SERIE D'INDOLYL-1,4-NAPHTHOQUINONES

Addition of an indole, which does not have a group at the 3-position, to 1,4-naphthoquinone leads to the expected 2-(3-indolyl)-1,4-naphthoquinone.When the 1,4-naphthoquinone is substituted at the 2-position by an alkyl or aryl group, the 2-substituted 3-(3-indolyl)-1,4-naphthoquinone is easily formed.However, when the 2-substituent of the quinone is functional (OH, OMe, Cl, Br, NC5H10, S-C6H5), in addition to the new series of expected indolylnaphthoquinones, several by-products resulting from elimination of the 2-substituted and/or further reaction of these compounds are formed.The outcome at the reaction appears to be very sensitive to the experimental conditions.

Naphthalene anti-psoriatic agents

Psoriasis in mammals is relieved by topically administering naphthalenes of the formula: STR1 wherein: R1 is lower alkoxy or optionally substituted phenoxy; R2 is hydrogen, lower alkyl, optionally substituted phenyl or optionally substituted phenyl-lower-alkyl; R3 is hydrogen, lower alkyl, lower alkoxy, halo, optionally substituted phenyl, optionally substituted phenyl-lower-alkyl or optionally substituted phenyl-lower-alkoxy, and m is 1 or 2; X and Y are different and are selected from the group consisting of hydrogen, R4 and -C(O)W, wherein W is alkyl of one to seven carbon atoms, optionally substituted phenyl or optionally substituted benzyl; and R4 is lower alkyl or optionally substituted phenyl-lower-alkyl.
