Different substituted furans are synthesized by cyclization of 4-pentynones using potassium tert-butoxide in DMF. A different reaction pattern is observed when the same componds were treated with sodium methoxide in MeOH. A new approach to 2-propargyl-carbonyl compounds is also proposed.

Abstract
Different substituted furans are synthesized by cyclization of 4-pentynones using potassium tert-butoxide in DMF. A different reaction pattern is observed when the same componds were treated with sodium methoxide in MeOH. A new approach to 2-propargyl-carbonyl compounds is also proposed.File in questo prodotto:
