3,5-Dioxopimelates as new synthetic building blocks. Cyclocondensation with 1,2-, 1,3- and 1,4-dinucleophiles
摘要:
Cyclocondensation reactions of 3,5-dioxopimelates, new and versatile synthetic building blocks, with hydrazines, urea, thiourea and phenylene-1,2-diamines allow for a convenient synthesis of various heterocycles containing two ester-substituted side-chains.
