Page 337. R for compounds 8b, 10b, and 11b in Table 1 and Scheme 3 should be CH 2 CH(CH 3 ) 2 rather than CH(CH 3 ) 2 .The diastereoselectivities reported using isonitrile 1 with the arabinosyl auxiliary 9 are not significantly enhanced relative to those reported by Kunz and coworkers (ref 5b) using tert-butyl isocyanide at -78°C. In addition, Kunz and Pfrengle (J. Am. Chem. Soc. 1988, 110, 651-652 and ref 5a) report an example of an asymmetric Ugi reaction using phenylisonitrile that resulted in a 94:6 dr. We regret any perceived misrepresentation of the earlier work reported by Kunz and Pfrengle.

An Iron-Mediated Approach to o-Aryloxyanisoles. -Phenoxylation of (o-chloroanisol)cyclopentadienyliron hexafluorophosphate (I), previously obtained by monomethoxylation of the corresponding o-dichlorobenzene, is shown to be an efficient method for the synthesis of o-aryloxyanisole complexes (III) (7 examples). -(HOLDEN, MICHAEL S.; PETRICH, SAMANTHA R.; Tetrahedron Lett. 40 (1999) 23, 4285-4288; Dep.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
