Trans-Myrtanol

The adsorptive separation of pinenes on Zeolites is reported.303 The C-6 and C-7 13C n.m.r. chemical shifts in bicyclo[3,l,l]heptanes support other known conformational evidence and confirm that cls-pinane and ds-myrtanol (209 X = OH) have a bridged-boat conformation, that trans-myrtanol has a bridged-chair conformation, and that trans-2-pinanol and myrtenol (210 X = OH) have Y-shaped conformations verbenone (211 R R2 = O), and trans-verbenol (211 R1 = H, R2 = OH) give anomalous results which may be due to a conjugation effect the bridged-chair...

Incorporation of a chiral chain in the Schiff-base ligand led to the formation of a chiral crystal H phase, Cr 107.2 H 148.9 I and Cr 113 H 132.3 I, for both complexes 104b bearing the citronellol or the 2-octanol chain (104b R = OR ), respectively recall that both imine ligands exhibited a SmC phase (Cr 50.4 SmC 77.3 I and Cr 47 SmC" 48 I). In this case, the N,N-trans N,N-cis ratio was 9 1. Ligands and complexes with bulky chiral chains like (—l-rw-myrtanol or (—(-menthol were not liquid crystalline.
