Synthesis of 3,3-disubstituted Tetrahydroisoquinolines (THIQs) via Base-mediated [4 + 2] Annulation
In this research we represented a simple and elegant method for 3,3-disubstituted THIQs via base-mediated [4 + 2] annulation of α-amino acid ester derivatives and 1,2-bis(bromomethyl)benzene under mild conditions. This protocol features good substrate tolerance, mild conditions and moderate to excellent yields. The synthetic potential of this protocol was highlighted by scale-up experiments and further structural elaboration.
期刊介绍:
Organic chemistry is the fundamental science that stands at the heart of chemistry, biology, and materials science. Research in these areas is vigorous and truly international, with three major regions making almost equal contributions: America, Europe and Asia. Asia now has its own top international organic chemistry journal—the Asian Journal of Organic Chemistry (AsianJOC)
The AsianJOC is designed to be a top-ranked international research journal and publishes primary research as well as critical secondary information from authors across the world. The journal covers organic chemistry in its entirety. Authors and readers come from academia, the chemical industry, and government laboratories.
