Additions and Corrections Vol. 62, 1997 Nicola M. Howarth and Laurence P. G. Wakelin*. R-PNA: A Novel Peptide Nucleic Acid Analogue of DNA

Page 5442. With respect to the paragraph beginning “During the course of our work....”, it has been brought to our attention that the chiralities of the glutamic acid and subsequent R-PNA have been inadvertently misreported. The paragraph should now read: During the course of our work, Lenzi et al.21,22 presented a preliminary report on the preparation of an R-PNA in which the base-amino acids are derived from L-glutamic acid.21 This results in an R-PNA of identical chirality (i.e., L-) to that described here.

A General and Facile Synthesis of Substituted Furans by Palladium-Catalyzed Cycloisomerization of (Z)-2-En-4-yn-1-ols.

Page 7688, left column, line 12. The following sentence should have been added after the full stop: “The Agcatalyzed cycloisomerization of (Z)-2-en-4-yn-1-ols bearing an internal triple bond substituted with an alkyl group has been described: Marshall, J. A.; Sehon, C. A. J. Org. Chem. 1995, 60, 5966-5968.” We have inadvertently omitted this paper in our reference citations. JO994013A 10.1021/jo994013a Published on Web 12/29/1999
