摘要：

Analysis of the H-1 and C-13 NMR spectra of the labeled hemiacetal [3a,8a-C-2(13)]1 showed that this compound exists in solution in equilibrium with the benzopyran derivative 2. This equilibrium was exploited for an alternative preparation of the furo[2,3-b]benzofuran fragment present in aflatoxins.
