Matzo Matzo Matzo, matzah, or matza ( "matsoh", "matsa"; plural matzot; matzos of Ashkenazi Jewish dialect) is an unleavened flatbread that is part of Jewish cuisine and forms an integral element of the Passover festival, during which "chametz" (leaven and five grains that, per Jewish Law, can be leavened) is forbidden. As the Torah recounts, God commanded the Jews to create this special unleavened bread. During Passover it is eaten as a flat, cracker-like bread or used in dishes as breadcrumbs and in the traditional matzo ball soup. Matzo that is kosher for Passover is limited in Ashkenazi tradition to plain
Meta-selective C–H functionalization copper catalyzed C–H arylation. "Meta"-olefinated biologically important biphenyl, amino acid and Baclofen derivatives have been accessed by remote C–H activation assisted by the "end-on" template. These demonstrate the potential applications of meta-selective C–H functionalization in medicinal chemistry. Meta-selective C–H functionalization "Meta"-selective C–H functionalization refers to the regioselective reaction of a substituted aromatic ring on the C–H bond "meta" to the substituent. Substituted aromatic ring is an important type of substructure in pharmaceuticals and industrial compounds. Thus, synthetic methods towards substituted aromatic rings are always of great interest to chemists. Traditionally, regioselectivity on the aromatic ring is achieved by the electronic
