実験手順

0.48 g (69 millimoles) of lithium and 9 g (150 millimoles) of ethylenediamine were reacted in the atmosphere of air at a temperature of 128°-133° C. for 4 hours, and then mixed with 82 g of the above-prepared sabinene oil containing 35.7 g (262 millimoles) of (+)-sabinene. The mixture was allowed to react for 6 hours at 130° C. The reaction mixture was treated as described in Example 1 and thereafter, subjected to distillation at 60°-75° C. and 30 mmHg, affording 56.8 g of α-thujene oil containing 47.8% of (-)-α-thujene. The yield of (-)-α-thujene was 76.0%.
