Synthesis of Polycyclic Aromatics from a Diiodosultine by Suzuki-Miyaura Cross-Coupling and Diels-Alder Reaction
摘要:
A convergent synthesis of polycyclic aromatic compounds by the application of Suzuki-Miyaura cross-coupling and Die Is-Alder reaction as key steps is described.
The development of an oxa-Diels–Alder reaction between sultines and carbonyl compounds is reported. o-Quinodimethanes, generated from sultines, undergo a [4+2]-cycloaddition with activated aldehydes or ketones in the presence of Cu(OTf)2 to provide a variety of functionalized isochromans, including spiroisochromans, in up to 99% yield. The developed protocol demonstrates broad functional-group compatibility

Syntheses of 3-Aryl Tetrahydroisoquinolines via an Intermolecular [4 + 2] Cycloaddition of Sultines with Imines
The development of an intermolecular aza-Diels–Alder (DA) cycloaddition of sultines and imines is reported. By exploiting sultines as o-quinodimethane precursors and aryl imines as dienophiles in the presence of Cu(OTf)2, an aza-DA reaction proceeds to provide a wide variety of 3-aryl tetrahydroisoquionlines in moderate to excellent yield (up to 89%). The synthetic utility of these products was demonstrated
