Isoxazoles amino acids containing

This table lists mushroom species known to contain unusual isoxazole amines. The mushrooms in the first section are all definitely entheogenic (see Coyote Man Brother William 1972 Pericgla 1985 Fericgla 1992 Festi 8c Bianchi 1992 Heinrich 1992 Heinrich 1995 Larris 1980 Leonhardt 1992 Ott I97(Sa Pollock 1975B) and these contain as active principles the amino acid ibotenic acid (named for ibo-tengu-take, the Japanese common name fot Amanita strobilifirmis, from which it was first isolated, and relating the mush-... 

The first report of the use of cellulose beads as support for microwave-assisted SPOS was published in 2003 and described the generation of a library of pyrazoles and isoxazoles [49]. The synthesis was performed using commercially available amino cellulose (Perloza VT-100) containing aminoaryl ethyl sulfone groups in flexible chains (Scheme 16.27). Initially, the solid support was treated with excess formyl imidazole and the corresponding yS-keto compounds to generate cellulose-bound enaminones in a one-pot Bredereck-type condensation. The reaction was catalyzed by (+)-camphor-10-sulfonic acid (CSA) and performed under microwave-irradiation conditions in an open vessel to enable the methanol formed to be removed from the reaction equilibrium [49].
