The Chemistry of Laurenene. XII. The Structure of a Minor Product From the Formic Acid Induced Rearrangement of Lauren-1-ene

Abstract

Rearrangement of lauren-1-ene (1) with formic acid gives a trisubstituted alkene (4) in addition to the previously characterized tetrasubstituted alkene (3). The structure was determined by n.m.r . Studies on (4) and the derived diol (5). Alkene (4) contains a new tetracyclic carbon skeleton which comprises one six- membered ring and three five- membered rings.
