An improved synthesis of alpha-carbolines under microwave irradiation.

[reaction: see text]. Alpha-carbolines are interesting core structures for designing DNA-interacting small molecules. However, these compounds are not commercially available and their synthetic methods are low yielding or time consuming. The shortest synthetic route, the modified Graebe-Ullmann reaction, has been optimized by using microwave heating in four different types of apparatus to give shorter reaction times and enhanced yields. Optimized conditions enabled the preparation of a small library of alpha-carbolines.

Westphal reaction in solid-phase.

[reaction: see text]. A library of cycloimonium salts has been prepared through Westphal reaction in solid-phase. By reaction of solid-support-bound azolium or azinium acetates 2, 1,2-diketones 4, and base, cycloimonium salts 5 were synthesized in good to high yield and purities.
