Area of Science:

Natural Product Chemistry
Organic Chemistry
Phytochemistry

Background:

Bee-collected pollen is a rich source of diverse natural products.
Furan derivatives are known for their varied biological activities.

Purpose of the Study:

To isolate and characterize new furan derivatives from rape pollen.
To determine the structures and absolute configurations of the isolated compounds.

Main Methods:

Extraction of rape pollen using ethyl acetate.
Structure elucidation via comprehensive spectroscopic analysis (e.g., NMR, MS).
Determination of absolute configurations using Snatzke's method with dimolybdenum tetraacetate.

Main Results:

Isolation and identification of two new furan derivatives, named pollenfurans A (1) and B (2).
Complete structural elucidation of compounds 1 and 2.
Confirmation of the absolute configurations of the 6,7-diol moiety in both pollenfurans.

Conclusions:

Pollenfurans A and B represent novel chemical entities discovered in rape pollen.
The study expands the known repertoire of furan derivatives from natural sources.
The methodology provides a reliable approach for determining the absolute configuration of similar compounds.
