Synthesis of 5: H -chromeno[3,4- b] pyridines via DABCO-catalyzed [3 + 3] annulation of 3-nitro-2 H -chromenes and allenoates

2021, European Journal of Medicinal ChemistryCitation Excerpt :Therefore, we explored 2-butynoates (e.g. methyl and ethyl 2-butynoate) as an alternative to allenoates to act as formal 1,3-dipole precursor in the synthesis of the new spirocyclopentenyl-β-lactams. Although the use of 2-butynoates as dipole precursors in phosphane-catalyzed [3+2] annulation reactions is known [20–23], the reactivity towards 6-alkylidenepenicillanates is unexplored. Initially, the reaction of 6-alkylidenepenicillanate 10 with ethyl 2-butynoate (13a) was attempted, under the reaction conditions used in the synthesis of molecule 1 with benzyl 2,3-butadienoate (11) [17].
