Popis | In the paper we present results of experiments with phenanthridinium family azomethine ylides in 1,3-dipolar cycloadditions. An influence of N-substitution on carbamoylmethylfenanthridinium cation and subsequently on the ylid upon the stereochemistry of 1,3-dipolar cycloadducts with various dipolarophiles was searched.Another search was done on systems with alkoxycarbonyl derivatives. When a group with stereogenic centre ((-)-mentyl) was introduced into phenanthridinium cation, the formed ylid reacted with dipolarofiles that way that only one diastereomer was formed. |
