Chemistry is traditionally divided into organic and inorganic chemistry. Formula: C4H4O3, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent£¬Which mentioned a new discovery about 4971-56-6
Synthesis of (¡À)-camptothecin using a [3+2] nitrone cycloaddition to construct the CDE ring moiety
A novel synthesis to camptothecin is described. A Friedlander condensation of o-aminobenzaldehye with tricylclic ketone affords camptothecin after further elaboration. Tricyclic ketone is prepared via a route employing a [3+2] nitrone cycloaddition and an intramolecular Knoevenagel condensation. A novel synthesis to camptothecin is described. A Friedlander condensation of o-aminobenzaldehye 2 with tricylclic ketone 3 affords camptothecin after further elaboration. Tricyclic ketone 3 is prepared via a route employing a [3+2] nitrone cycloaddition and an intramolecular Knoevenagel condensation.
