Photooxygenation of the cycloheptatriene derivative 9 gave the bicyclic endoperoxide 14. Cleavage of the peroxide linkage in 14 with thiourea resulted in the formation of 16. Treatment of the endoperoxide 14 with a catalytic amount of triethylamine provided a new isomer of stipitatic acid 11, and 16. Pyrolysis or the CoTPP (TPP = tetraphenylporphyrin) catalyzed reaction of 14 resulted in the formation of iso-stipitatic acid 10, and 18,

On continuous dependence on coefficients of the Brinkman-Forchheimer equations
Celebi, A. O.; Kalantarov, V. K.; Ugurlu, D. (2006-08-01)
We prove continuous dependence of solutions of the Brinkman-Forchheinier equations on the Brinkman and Forchheimer coefficients in H-1 norm.
A note on a theorem of Dwyer and Wilkerson
Öztürk, Semra (Springer Science and Business Media LLC, 2001-01-03)
We prove a version of Theorem 2.3 in [1] for the non-elementary abelian group Z(2) x Z(2n), n greater than or equal to 2. Roughly, we describe the equivariant cohomology of (union of) fixed point sets as the unstable part of the equivariant cohomology of the space localized with respect to suitable elements of the cohomology ring of Z(2) x Z(2n).
On the discretization of Laine equations
Zheltukhın, Kostyantyn (2018-01-01)
We consider the discretization of Darboux integrable equations. For each of the integrals of a Laine equation we constructed either a semi-discrete equation which has that integral as an n-integral, or we proved that such an equation does not exist. It is also shown that all constructed semi-discrete equations are Darboux integrable.
A new and efficient synthesis of indenone
Zengin, M; Dastan, A; Balcı, Metin (2001-01-01)
Reaction of dichloroketone 2 with NEt3 gave indenone (4) in high yield. Catodic reaction of 2 in the presence of C/Pt electrodes afforded the rearranged product 3 in high yield besides a small amount of chlorohydroxyketone 5. Reaction of rearranged dichloroketone 3 with NEt3 provided indenone (4) as the sole product. The mechanism of these reaction was discussed.
A note on the products ((m+1)(2)+1)((m+2)(2)+1) ... (n(2)+1) and ((m+1)(3)+1)((m+2)(3)+1) ... (n(3)+1)
Gurel, Erhan (2016-05-01)
We prove that for any positive integer m there exists a positive real number N-m such that whenever the integer n >= m neither the product P-m(n) = ((m + 1)(2) + 1) ((m + 2)(2) + 1) ... (n(2) + 1) nor the product Q(m)(n) = ((m + 1)(3) + 1)((m + 2)(3) + 1) ... (n(3) + 1) is a square.
