Stereocontrolled synthesis of kelsoene by the homo-favorskii rearrangement.
[reaction: see text] (+/-)-Kelsoene (4) has been synthesized from 2,5-dihydroanisole in 16 steps in 12.5% overall yield. The key step involves a base-catalyzed reaction of gamma-keto tosylate (5), which effects a homo-Favorskii rearrangement to 16 as well as the corresponding intramolecular S(N)2 product 15 from the enolate of 5. Ketone 15 can efficiently be isomerized to cyclobutanone 17 havin...

متن کاملdeterminant of the hankel matrix with binomial entries
abstract in this thesis at first we comput the determinant of hankel matrix with enteries a_k (x)=?_(m=0)^k??((2k+2-m)¦(k-m)) x^m ? by using a new operator, ? and by writing and solving differential equation of order two at points x=2 and x=-2 . also we show that this determinant under k-binomial transformation is invariant.

abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
