摘要
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.
