要：A versatile and operationally simple base-catalyzed multi-component
domino reaction between α,β-unsaturated carbonyl compounds, aldehydes,
and alcohols is described, providing a new efficient, and
stereoselective one-pot preparation of trisubstituted alkenes and
1,3-dienes. |

要：Oxacycloisomerization of 1-hydroxy-2-propargyl cyclic derivativeswas
catalyzed by the first-generation Grubbs catalyst (Grubbs I)and led to
good yields of bicyclic dihydrofurans. Tricyclicacetals were also
obtained from cyclic alkyne diols using the sameexperimental procedure. |

要：The reaction of 1-trimethylsilylbuta-2,3-diene with tin
tetrachloride, antimony trichloride or antimony pentachloride gave the
corresponding buta-1,3-dien-2-yl halostannane or stibine derivatives;
this ligand exchange was extended to other β-allenylsilanes. |

University of Oran (
Arabic: جامعة وهران,
French:
Université d'Oran), or
Es Sénia University (
Arabic: جامعة السانية), is a university located in western
Algeria in the
wilaya of Oran.
It was established in November 1961 as part of the University of
Algiers. On April 13, 1965 was made a separate campus, and on December
20, 1967 it became an independent University. It was the first
university established after the independence of Algeria.
Oran
University is one of the most important and largest universities in
Algeria. It annually graduates thousands of students in all disciplines
from all over Algeria and other Arab and foreign countries. The
university also provides scientific and pedagogical supervision to many
other universities and university centers in western
Algeria.
