Base exchanges occurred in an additional eight positions resulting in an overall homology of 87%. Similar evolutionary processes can be deduced from the tRNA)~N sequence. The Locusta gene of 70 nucleotides is 3 bp longer due to two base insertions in the T~PC and a third in the V loop. An additiona
## Abstract The synthesis of (5__S__,9__S__)‐5,9‐dimethylheptadecane (1) as well as that of (5__S__,9__S__)‐5,9‐dimethyloctadecane (2) has been achieved by starting from methyl (__R__)‐3‐hydroxy‐2‐methylpropanoate (3a) and (__S__)‐citronellal (7).
All of the stereoisomers of 10,14-dimethyloctadec-1-ene (1), (Lyonetia prunifoliella), were synthesized by starting from the enantiomers of citronellol (4) and methyl 3-hydroxy-2-5,9-dimethyloctadecane (2) and 5,9-dimethylheptadecane (3), the sex pheromone components of the apple leafminer methylpro
