The Chemistry of Laurenene. VIII. Laurena-1(15),2-diene, Laurena-1,14-diene and Lauren-1(15)-ene

Abstract

The naturally occurring diterpene lauren-1-ene (1a) has been converted into its thermodynamically less stable isomer, lauren-1(15)- ene (3), via laurena-1(15),2-diene (5). Laurena-1,14-diene (7) was also synthesized. Conformational mobility in some of these laurenane systems has been revealed in their ¹³C n.m.r. spectra.
