An interval representation (or simply representation) R of a graph G is a collection of finite sets $\{R(\nu):\nu \in V(G)\}$ of closed bounded intervals so that $u \leftrightarrow \nu$ if and only if there exist $\theta\sb{u} ... application/pdf PDF (5MB) • (1966) A spark chamber experiment was performed at the Argonne National Laboratory Zero Gradient Synchrotron to study the polarization of the muon in the decay KL. The results of the test of time reversal in variance and the ... application/pdf PDF (3MB) • (1966) application/pdf PDF (3MB) • (1996) Turfgrass growth retardants, trinexapac-ethyl, flurprimidol and paclobutrazol were treated in an initial greenhouse study but only trinexapac-ethyl was included in subsequent field and greenhouse experiments. Applications ... application/pdf PDF (5MB) • (1978) application/pdf PDF (2MB) • (1996) A short and efficient asymmetric synthesis of the pyrrolizidine necine base (${-}$)-hastanecine is described. The key reaction in the synthesis is a sequential inter (4+2) /inter (3+2) cycloaddition. The Lewis acid promoted ... application/pdf PDF (12MB) • (1969) application/pdf PDF (5MB) • (2008) Experiments were also carried out to establish if dykellic acid's biological activity can be attributed to either of two well-established mechanisms, ROS quenching or caspase inhibition. Using fluorescent dyes sensitive ... application/pdf PDF (3MB) • (2013-05-28) Taking advantage of the inherent modularity present in the majority of small molecule natural products, we envision that a building block based approach involving the iterative cross-coupling of MIDA boronate containing ... application/pdf PDF (13MB) • (1972) application/pdf PDF (4MB) • (2000) The first synthesis of (+)-casuarine, a pentahydroxy pyrrolizidine alkaloid of the alexine/australine subclass, is described. The key step is a tandem inter [4+2]/inter [3+2] nitroalkene cycloaddition involving an oxygenated ... application/pdf PDF (9MB) • (1981) The synthesis of four related sesquiterpenes was accomplished by elaboration of the chiral precursor pulegone. The ring system of (-)-prezizaene and (-)-prezizonal was constructed by intramolecular ring expansion of a diazo ... application/pdf PDF (5MB) • (2019-12-09) It is well-known that a diet rich in omega-3 fatty acids, such as docosahexaenoic acid (DHA), promotes a wide range of beneficial health effects. Two of DHA’s metabolites, epoxydocosapentaenoic acid-ethanolamide (EDP-EA) ... application/pdf PDF (4MB) • (1991) A total synthesis of 9,10-syn copalol (181) from silyl phosphonate 76 was accomplished in 11 steps with an overall yield of 6.6% (Scheme 54). The key transformation involved electrophilic cyclization of epoxy silyl triene ... application/pdf PDF (8MB) • (2016-12-08) Lycoricidine a member of the amaryllidaceae isocarbostyril alkaloid family of natural products isolated from bulbs of plants in the amaryllidaceae family, which include the common daffodil. The compound has been demonstrated ... application/pdf PDF (6MB) • (1979) application/pdf PDF (5MB) • (1990) Didemnin A, a cyclic depsipeptide isolated from a Caribbean tunicate, was synthesized by coupling two key fragments, (Boc-(3S,4R,5S)-Ist(TBDMS)-(2R,S;4S)-Hip-Leu-Pro-OH (Fragment I)) and (Z- scD-MeLeu-Thr(H-Me$\sb2\$Tyr)-OTMSe) ...
