| Abstract: | Base-catalyzed reaction of 2-hydroxybenzaldehyde with 2-{2-(vinyloxy)ethoxy]methyl}oxirane gave 2-{2-hydroxy-3-2-(vinyloxy)ethoxy]propoxy}benzaldehyde in 42% yield, and subsequent condensations of the product with thiosemicarbazide and primary aliphatic amines afforded the corresponding thiosemicarbazone (yield 86%) and 1-{2-(alkylimino)methyl]phenoxy}-3-2-(vinyloxy)ethoxy]propan-2-ols (74–81%). |
