- One-step synthesis of new 3-oxa- or 3-azabicyclo[3.2.0]hept-5-en-2,7-dione and 5,9-dioxa- or 5,9-diazabicyclo[5.3.0]dec-1-en-3 -methyliden-6, 8-dione derivatives

In this work we describe the synthesis of new compounds of a 3-oxa- or 3-azabicyclo[3.2.0]hept-5-en-2,7-dione (3a-d) and 5,9-dioxa- or 5,9-diazabicyclo[5.3.0]dec-1-en-3-methyliden-6,8-dione (4a-d) type with potential biological activity, obtained from the reaction of 2-propyn-1-ol or 2-propynylamine derivatives (1a-d) with carbon suboxide (2) in various molar ratios.
