10 422 incorrectly names (170; R1= Me, R2 = Ph)]. * Chemical Abstracts does not use the prefix 'iso' used in these Reports. Terpenoids and Steroids 36 (170) (170; R'= Me or Ph, R2= Ph) have the two dipoles, C=O and C=S, unfavourably aligned by steric constraints. d. r. r. r. Vol. 5, p. Vol. 3, p. 59 for related work). The previously reported (Vol. 4, p. 44; cf. Vol. 5 , p. 3 1) lower stereospecificity reported by Stothers for the racemization of camphene with acid may be interpreted as involving less internal stabilization of (171) via C-2-C-6 bonding in the presence of the more nucleophilic solvent used.
