Li. Zakharkin et Im. Churilova, SYNTHESES OF 2-OXABICYCLO[4.10.0]HEXADEC-1(6)-ENE FROM CYCLODODECANONE, Russian chemical bulletin, 43(4), 1994, pp. 608-611
Two methods for the synthesis of 2-oxabicyclo[4.10.0]hexadec-1 (6)-ene
from cyclododecanone have been suggested. The most convenient method
involves the preparation of 2-(3-tert-butoxypropyl)cyclododecanone by
phase-transfer catalyzed alkylation of cyclododecanone with 1-bromo-3-
tert-butoxypropane followed by removal of the protecting tert-butyl gr
oup and elimination of water.
