Generation of a Small Library of Highly Electron-Rich 2-(Hetero)aryl-SubstitutPhenethylamines by the Suzuki—Miyaura Reaction: A Short Synthesis of an
45- 104 ed
Apogalanthamine Analogue. — A variety of electron-rich, neutral, and electron-poor
phenyl and heteroaryl rings are introduced at the 2-position of the highly electron-rich
bromide (I) by the title reaction. Microwave irradiation is used to enhance yields and
reaction rates. The coupling of (I) with the hindered boronic acid (IV) is also successfully accomplished, even in water as solvent. The resulting biaryl is transformed into
tricycle (VII), a member of the Amaryllidacae alkaloid family. — (APPUKKUTTAN,
