PTC-alkylation and Michael addition of indanones; Synthesis of 2-substituted indanones

摘要

The reactivity of indan-1-one (1a) and/or indan-1,3-dione (1b) towards alkylation in the absence or presence of carbon disulphide under phase transfer catalysis (PTC) conditions has been investigated to give indanone derivatives 2-9. Michael addition of(1a,b) to alpha,beta-unsaturated carbonyl compounds under the same PTC conditions yielded the adducts 10-16. [References: 8]
