Additions and Corrections Page 5225. The heading of the fourth column of Table I11 should be 1 / 2 rather than 2/1. Vol. 47, 1982
Harold Kwart* and Ann G. Horgan. Evidence for Proton Tunneling in Strong Base Promoted (Stepwise) @-Elimination Reactions. Page 159. Column 1, summary 1.8: change 1.197 to 1.228. Page 159. Column 2, table I, footnote d change 1.197 to 1.228. Page 161. Column 1,figure 1legend, 1.29 change 0.21 to 0.163. Page 161. Column 1,figure 1legend, 1.33: change 0.3 to 0.35.
R. Daniel Little,* Roland Verh6,f William T. Monte, Seln Nugent, and James R. Dawson. MIRC Reactions. 3. Use of Doubly Activated Substrates. Page 362. Column 2, Scheme 11. The line formulas in the lower right-hand corner of the scheme should read NuCH2CH2C02R + -OH,not NuCHzCHCOzR + -OH. Page 363. Column 1. The compounds should be numbered la, lb, and 2, not la, lb, and IC.
Marshall Gates. Condensation of Naphthcquinones with Polar Ethylenes. A Reexamination. Page 578, column 1. The first sentence of the second paragraph of this note which reads as printed "A reexamination of these substances with the aid of instrumental techniques unavailable a t the time of the original work has para-disubstituted phenyl certain of the structural assignments are incorrect" is unintelligible. It should be altered by deleting "para-disubstituted phenyl" and inserting "shown that". Also the number 1 designating the upper structure on the right-hand column of page 578 is missing.
Sheldon E. Cremer* and Craig Blankenship. Preparation and Characterization of 2-Silanorbornanes. Page 1628. Column 2. The structures in this column appear as 2-silabicyclo[2.2.1]heptanes;these should be drawn as 3-silabicyclo[3.2.l]octanes as stated on line 13 (from the top) of this column.
Aluru S. Sarma* and Partha Chattopadhyay. Synthetic Studies of trans-Clerodane Diterpenoids and Congeners: Stereocontrolled Total Synthesis of (*)-Avarol. Page 1727. The few descriptions relating to the stereochemical assignments, based on the conversion of compound 7b to the keto ester 8, should be ignored in the light of the details recently published by Sullivan and Faulkner (Tetrahedron Letts. 1982, 23,907-910). However, the stereochemistry of all the described synthetic compounds, including 7b and 8, remains valid (cf. ref 23, cited in the publication).

Use of Nitrogen-15 Shifts as an Aid in Stereochemical Analysis of These Heterocyclic Systems.. Page 1935. Scheme 11. The upper right structure labeled 1' should be li' (and atom 1should be oxygen instead of CH,); the lower structure labeled 1" should be li".
