Literature References
Friedel-Crafts reaction with arenes gives 3-aroylpropionic acids: Org. Synth. Coll., 2, 81 (1943). For a review of the Friedel-Crafts reactions of the anhydrides of dibasic acids, see: Org. React., 5, 229 (1949). For reaction with phosphoranes, in a route to 2,2-disubstituted cyclopentane-1,3-diones, see (1-Ethoxycarbonylethylidene)triphenylphosphorane, A15619. A method for protecting both H atoms of a primary amine consists of formation of the succinimide, followed by enolsilylation with Triisopropylsilyl trifluoromethanesulfonate, B21127, to form the 2,5-bis(triisopropylsiloxy)pyrroles. Deprotection can be effected by desilylation with dilute HCl, followed by hydrazinolysis: Tetrahedron Lett., 38, 2617 (1997).
