Abstract

The iodheterocyclization of 4-dialkylaminomethyl-1,6-heptadien-4-oles takes place with participation of nitrogen of amino-group and binary bond of the one of amino-radicals with formation of 1,1-dialkyl-2-iodmethyl-4-allyl-4-oxypirrolidiniums iodides with high output. The bromhetrocyclization of above-mentioned aminoalkenoles flows with participation of two amino- and hydroxy-groups and two allyl binary bounds with formation of 1,1-dialkyl-2-brommethyl-4-spiro(2’-tetrahydro-4-bromfuril) pyrrolidiniums bromides with low output.
