Vk. Brel, Synthesis and cyclization of diethylphosphono-substituted alpha-allenic alcohols to 4-(diethylphosphono)-2,5-dihydrofurans, SYNTHESIS-S, (3), 1999, pp. 463-466
Various types of diethylphosphono-substituted alpha-allenic alcohols have b
een readily prepared. Treatment of these compounds with a catalytic amount
of silver nitrate under a nitrogen atmosphere provided the corresponding 4-
(diethylphosphono)-2,5-dihydrofurans.
