N-Allylamides and allyl esters of bisalkoxycarbonylaminoacetic acid (5) were found to cyclize in strong acid solutions to the five-membered pyrrolidones (6; Y = NH) and butyrolactones (6; Y = O) rather than to the corresponding six-membered piperidinones (8; Y = NH) or the six-membered lactones (8, Y = O).
Ñ -Allylamides和bisalkoxycarbonylaminoacetic酸(的烯丙基酯5)被发现环化在强酸溶液到五元吡咯烷酮(6 ; Y = NH)和丁内酯(6 ; Y = O),而不是相应的六元哌啶酮(8 ; Y = NH)或六元内酯(8,Y = O)。
