Synthe1sis of 5-epi-arizonin B1 and 5-epi-arizonin C1
摘要:
The first synthesis of 5-epi-arizonin B1 (19) and 5-epi-arizonin C1 (18) is described in which the key step involves rearrangement of a furo[3,2-b]naphtho[2,1-d]furan (16) to a furo[3,2-b]naphtho[2,3-b]naphtho[2,3-d]pyran (17). Regioselective synthesis of naphthoquinone (15) was crucial to this synthetic strategy.

The synthesis of several analogues of (+/-)-semivioxanthin including five thiophene analogues, using directed metalation are reported. The strategy consisted of the synthesis of functionalized naphthalene or benzo[b]thiophene as building blocks followed by annelation of the pyrone. (C) 2003 Elsevier Science Ltd. All rights reserved.
