Gerstenberger, Ina published the artcileRegioselective and stereoselective transformations of enantiopure para-benzoquinone equivalents, Synthetic Route of 5034-06-0, the publication is European Journal of Organic Chemistry (1998), 643-650, database is CAplus.
The selectivities of typical transformations of the 1,4-benzoquinone Diels-Alder adduct I (RR1 = bond) and its dihydro derivative I (R, R1 = H) are highly dependent on the mechanistic path followed. To avoid ambiguities and to make sure of clearly defined regioselectivity, 1,4-benzoquinone monoethylene ketal was examined and proven not only to be an excellent dienophile but, of course, also to lead to reliable regioselectivity in subsequent transformations. This led to the correction of an earlier provisional assignment of alkylation products.
