- On the Synthesis and Reactivity of 2,3-Dihydropyrrolo[1,2- a ]quinazolin-5(1 H)-ones
-
An improved, scalable synthetic route to the quinazolinone natural product 2,3-dihydropyrrolo[1,2-a]quinazolin-5(1H)-one is reported. The applicability of this method to analogue synthesis and the synthesis of related natural products is explored. Finally, reactivity of the scaffold to a variety of electrophilic reagents, generating products stereoselectively, is reported.

- SYNTHETIC ANALOGS OF Peganum ALKALOIDS. I. SYNTHESIS OF METHOXY- AND HYDROXY-SUBSTITUTED DEOXYVASICINONES AND DEOXYPEGANINES
-
6-Methoxy-, 7-methoxy-, and 8-methoxydeoxyvasicinones have been synthesized by the reaction of substituted (3-methoxy-, 4-methoxy-, and 5-methoxy-) anthranilic acids with α-pyrrolidone.The demethylation of these compounds has given the corresponding hydroxy-substituted analogs of deoxyvasicinone, and the reduction of the products obtained with zinc in hydrochloric acid has given the hydroxy- and methoxy- analogs of deoxypeganine. 8-Hydrooxydeoxypeganine dimethyl-, ethyl-, and butylcarbamates have been obtained by the carbamoylation of 8-hydroxydeoxypeganine.
