Abstract

AbstractA synthetic method for the preparation of selenoglycolurils is reported. Target compounds were obtained by two‐stage transformation of unsubstituted, 1‐substituted and 1,3‐disubstituted thioglycolurils by S‐methylation with MeI to the corresponding isothiouronium salts (Step 1) followed by selenation with NaHSe generated in situ from grey Se and NaBH4 (Step 2). Selenoglycolurils possessed potent antifungal activity against Candida albicans and Cryptococcus neoformans (MIC 0.25–0.125 μg/mL) with no discernable toxicity against mamallian cells, supporting the unique role of organoselenium compounds as novel antifungal agents.
