Metal-Catalyzed Cycloisomerization Reactions of cis-4Hydroxy-5-alkynylpyrrolidinones and sis-5-Hydroxy-6-alkynylpiperidinones: Synthesis of Furo[3,2-b]pyrroles and Furo[3,2-b]pyridines [J. Org. Chem. 2009, 74, 5523. DOI: 10.1021/ jo9007942]. Jasmine C. Jury, Nalivela Kumara Swamy, Arife Yazici, Ian R. Morgan, Anthony C. Willis, and Stephen G. Pyne* Page 5523. One author’s name, Ian R. Morgan, was accidently omitted. The correct list of authors is as follows: Jasmine C. Jury,† Nalivela Kumara Swamy,† Arife Yazici,† Ian R. Morgan,† Anthony Willis ‡ and Stephen G. Pyne*,† † School of Chemistry, University of Wollongong, Wollongong, New South Wales 2522, Australia. ‡ Research School of Chemistry, Australian National University, Canberra, ACT 0200, Australia.

An Improved Synthesis of the Selective EP4 Receptor Agonist ONO-4819 [J. Org. Chem. 2009, 74, 8298.DOI: 10.1021/ jo901497u]. Chisa Ohta,*, Shin-itsu Kuwabe, Tai Shiraishi, Ikuo Shinohara, Hiroshi Araki, Shigeru Sakuyama, Takayuki Makihara, Yasufumi Kawanaka, Shuichi Ohuchida, and Takuya Seko Page 8299, column 1, line 6. “BINOL-H” should be corrected to read “BINAL-H”. Page 8301, column 1, line 9. The phrase “Reduction with NaBH4 with a catalytic amount of L-TarB-NO2,11 derived from tartaric acid, gave poor diastereoselectivity (entry 7).” should be corrected as follows: “Reduction with NaBH4 in the presence of L-TarB-NO2,11 derived from tartaric acid, gave poor diastereoselectivity (entry 7).” Page 8301, Table 2, entry 8. “RuCl 2 [(R)-binap][(R)-daipenc]” should be corrected as follows: “RuCl[(S, S)-TsDPEN](p-cymene)”. (S, S)-TsDPEN indicates (1S, 2S)-N-(p-tolylsulfonyl)-1,2-diphenylethylenediamine. DOI: 10.1021/jo902446x Published on Web 11/25/2009
