Abstract
| - A new method for β-phenol annulation involvingbase-induced [4C + 2C] cycloaromatization of readily available 4-bis(methylthio)-3-buten-2-one with a variety of cyclicand acyclic active methylene ketones has been reported.Appropriate choice of ketones allows synthesis of diverseframeworks such as dihydroindan, tetrahydronaphthalenes,their higher homologues, dihydro/octahydrophenanthrenes,anthracene, and heteroannulated analogue in high yieldswith regiocontrol of phenolic functionality.
