Efficient one-pot trans-dihydroxylation of 2H-pyrans using dimethyldioxirane (DMD): synthesis of trans-3,4-dihydroxy-3,4-dihydro-O-methyloctandreolones, orixalone D, and trans-3,4-dihydroxy-3,4-dihydromollugin natural products

An efficient one-pot formation of trans-diols on 2H-pyranyl rings was achieved by dimethyldioxirane in wet acetone. This new methodology was applied to the synthesis of natural products containing trans-diol on the pyranyl rings such as trans-3,4-dihydroxy-3,4-dihydro-O-methyloctandreolones, orixalone D, and trans-3,4-dihydroxy-3,4-dihydromollugin.
