Rearrangement of 1,2-divinyl-1,2-cyclohexanediol (I) was shown by Coda, et al (1) to give l-bicyclo[5.3.O]decen-2-one (II). We had made the ssme observation independently (2), but had also found that under milder conditions 7-hydroxybicyclo[5.3,0] decsn-2-one (III) can be isolated in good yield. In

β¦ Synopsis
Despite the fact that cyclobutylcarbinyl arenesulfonates solvolyze 102-lo3 times faster than appropriate models indicating carbon participation in the ionization, ' the nature of the product-forming intermediate has yet to be investigated in the parent system. We wish to report on the stereochemistry of nucleophilic attack on the rearranged cation derived from the cyclobutylcarbinyl system and indicate that net retention of configuration of the migration

In a previous Letter 111 the N-O acyl migration of cis-and trans-2--aminomethylcyclohexanol and cis-and trans-2-hydroxymetbylcyclohexylamine derivatives was reported. The present coamnznication deals with the stereospecific synthesis of the analogous cyclopentane derivatives, as well as the examinat

By treatment with organocopper reagents, N-activated 2,3-cis-3-alkyl-2-vinylaziridines produced exclusively (E)-allyl amines in high yields, presumably via an anti-SN2' reaction pathway. On the other hand, under otherwise identical conditions, N-activated 2,3-trans-3-alkyl-2-vinylazaridines gave an
