Synthesis of substituted cis decalins as potentials insect anti feedants

, : Synthesis of substituted cis decalins as potentials insect anti feedants. Journal of the Chemical Society Perkin Transactions I (5): 1516-1519

2.beta.-Acetoxy-1.alpha.-acetoxymethyl-5,5-dimethyl-1.alpha.,6.alpha.,10O.alpha.-bicyclo[4.4.0]decane-10-spiro-2'-oxiran (4) was prepared from 4,4-dimethylcyclohex-2-enone in 8 steps, 1 of which involves a useful Lewis acid-catalyzed cyclization of an acetylenic .beta.-oxo-ester (7). The strucuture of (4)was determined by X-ray crystallography. At a concentration of 1,000 ppm compound (4) showed a 72% inhibition of feeding by Locusta migratoria.

Background: Coronary vasoconstriction has been described after uncomplicated percutaneous transluminal coronary angioplasty (PTCA). However, it is still unknown whether this phenomenon is limited to coronary circulation. The present study was plan...
