✦ Synopsis

Abstract

A new product arising from the reaction of dichlorocarbene with norbornadiene, 6__endo__‐(2,2‐dichlorovinyl)‐cis‐bicyclo[3.1.0]hex‐2‐ene, is described. It does not arise from the normal exo‐l,2‐adduct, but possibly originates by sigmatropic rearrangement of an initially formed zwitterionic intermediate.

## Abstract The title reactions have been investigated in a static system. The addition of acetylene to cyclopentadiene (CPD) results in formation of norbornadiene (BCH), cycloheptatriene (CHT), and toluene (T), while BCH decomposition produces CPD, C~2~H~2~, CHT, and T.

The (Z)-(iodovinyl)oxetane 12 was prepared from d-glucose and the acyclic analog 18 was obtained from d-mannitol. Following the generation of their lithium derivatives by halogen-metal exchange, coupling to the enantiopure vinylsubstituted norbornanones 20, 23, and 29 proceeded exclusively via endo
