The work describes three principal Diels-Alder cycloaddition approaches toward chromanes that are designed for the de novo construction of the benzene ring. This study specifically focuses on the potential exploitation in the total synthesis of chromane-bearing natural products such as cebulactam A.
A selective and practical synthesis of nitroolefins
Jovel, Irina,Prateeptongkum, Saisuree,Jackstell, Ralf,Vogl, Nadine,Weckbecker, Christoph,Beller, Matthias
experimental part, p. 2493 - 2497 (2009/08/14)
A straightforward and general synthesis of nitroolefins from nitric oxide (NO) and olefins is presented. The direct nitration of aromatic olefins, allyl compounds, and acrylic acid derivatives proceeds smoothly at room temperature with high regioselectivity and good yields. The advantages of this novel procedure compared to established nitration procedures are demonstrated.
STEREOCHEMISTRY OF THE THIYLATION OF 1,2-DINITROALKENES AND 1,4-DINITRO-1,3-DIENES
Mukhina, E. S.,Berkova, G. A.,Pavlova, Z. F.,Lipina, E. S.,Perekalin, V. V.
, p. 1249 - 1254 (2007/10/02)
In thiylation with arenethiolates 1,2-dinitroalkenes form 1-nitro-2-arylthioalkenes in the more stable Z form, and in the absence of a base they form a mixture of the Z and E isomers.During thiylation with arenethiols 1,4-dinitro-1,3-butadienes only give (E,E)-1-nitro-4-arylthio-1,3-dienes.
β-SULFONYLNITROOLEFINS AS VERY REACTIVE ALKYNE-EQUIVALENTS IN DIELS-ALDER REACTIONS
Ono, Noboru,Kamimura, Akio,Kaji, Aritsune
, p. 1595 - 1598 (2007/10/02)
Very reactive dienophiles, β-sulfonylnitroolefins, are prepared starting from β-nitro alcohols.The high activation due to the nitro and the sulfonyl groups promotes the Diels-Alder reaction to various dienes under mild conditions.Reductive elimination of
