✦ Synopsis


Our interest in the tandem Claisen-ene rearrangement' and the desire to develop efficient methods for the control of both the regio-and stereochemistry of the ene reaction for eventual applications in organic synthesis led us to explore the role of the trimethylsilyl group as a controlling unit. I? CH2C02Et CH2C02Et CH2C02Et CH2C02Et r _z 3 4 a, R=H; b, R=TMS The four substrates, la_, a, &, and 2, were subjected to sealed tube thermolysis at 300Β°C in the presence of benzene-d6. The product distributions are listed in the Table.

Y-Shaped ambident dianions 1-6 were reacted with cyclization reactions generally proceeded with good regioselectivity which is controlled by the heteroatoms of the dielectrophilic oxalic acid-bis(imidoyl)dichlorides 7 providing a convenient access to novel N-heterocycles 8-13 dianion reagents. conta
