Fifteen novel β-lactams bearing the N-ethyl tert-butyl carbamate group 5a-o and fifteen N-(2-aminoethyl) β-lactams 6a-o were synthesized by the ketene-imine [2+2] cycloaddition reaction (Staudinger ). The cycloaddition reaction was found to be totally diastereoselective leading exclusively to the formation of the cis-β-lactam derivatives. These newly synthesized β-lactams were evaluated for the...
background: no consensus has been reached on prognostic value of serum concentration of β (beta) subunit of human chorionic gonadotropin (β-hcg) in treatment response to methotrexate in management of ectopic pregnancy. therefore, the present study aimed to evaluate this subject through a systematic review and meta-analysis. materials and methods: an extensive literature search on online databas...
