Phase-Transfer-Catalyzed Asymmetric Annulations of Alkyl Dihalides with Oxindoles: Unified Access to Chiral Spirocarbocyclic Oxindoles

A general phase-transfer-catalyzed asymmetric (n+1) (n = 4 or 5) annulation reaction, featuring the direct coupling of simple oxindoles with alkyl dihalides that are allylic/benzylic and non-allylic/benzylic, has been developed to provide previously inacc

Bromine-induced facile synthesis of butenolides and spirobutenolides from sterically congested tetrasubstituted dialkyl alkylidene succinates

Starting from sterically congested tetrasubstituted dialkyl alkylidene succinates, facile general approach to several dialkyl substituted butenolides and spirobutenolides with the generation of quaternary carbon center has been demonstrated via bromine-in

Photochromic fulgides: Part 3 - Synthesis and some photochemical reactions of diphenylmethylene substituted methylenesuccinic anhydrides

The pale yellow crystals of fulgides 5a, 5b, 5c, 5d and 5e in crystalline state and in solutions, change to red on irradiation at 366nm, this change is reversed on exposure to white light. The substituents on the methylene group have a remarkable effect on the absorption maxima of both the coloured and uncoloured forms.
