Abstract
A novel yclo[5.3.2.0.(4,9).0(4,11)]-dodec-1-yl]-2-butanone skeleton 3 has been synthesized by the treatment of 2-acetyl-3,4-dihydro-2,5-di ( 3 ''-oxo-butyl)-6-methyl-(2H)-pyran 2, with H-ZSM-5. However, the trea tment of compound 2 with p-TsOH gives bibenzyls. Present report provid es a unique acid catalysed cyclization of diketo-olefin system over ze olite, X-ray crystal structure of 3 is also presented. (C) 1998 Elsevi er Science Ltd. All rights reserved.
