(Chemical Equation Presented) The pseudohelical hydrocarbons (R)-6, (S)-7, and (R)-8 and the helical hydrocarbon (P)-9, formally derived from the helical hydrocarbon (P)-4 by stepwise replacement of each of the four-membered rings by a five-membered ring,
THE MAGNESIUM COMPLEXES OF 1,2-DIMETHYLENECYCLOALKANES: A NEW METHOD FOR A ONE-STEP SPIROANNELATION
Xiong, Heping,Rieke, Reuben D.
