摘要：

(5-alkyliden-2,3,3-trimethylpyrrolin-2-yl)diethylphosphonate 3 were obtained by rearrangement of (5-alkyl-2,3,3- trimethylpyrrolin-2 -yl)diethylphosphonate 2. Rearrangement of 2 was induced at high temperature under an inert atmosphere. This air sensitive transformation requires a methyl group on the alpha position adjacent to the phosphonyl group. These results give new insight into cyclization of beta-allenylaminophosphonates 1.
