Two new furan derivatives from bee-collected rape pollen

J Asian Nat Prod Res. 2011 Oct;13(10):930-3. doi: 10.1080/10286020.2011.600693.

Abstract

Two new furan derivatives named pollenfurans A (1) and B (2) were isolated from the ethyl acetate extract of bee-collected rape pollen. Their structures were elucidated by spectroscopic analysis. The absolute configurations of the 6,7-diol moiety in both compounds 1 and 2 were confirmed by Snatzke's method, observing the induced circular dichroism after the addition of dimolybdenum tetraacetate in DMSO.
