(9Z)-Dodec-9-en-12-olide (1), also known as ''Yuzu lactone'', a volati
le ingredient of Yuzu fruit was prepared in a three step synthesis via
Z-selective Wittig olefination, a deprotection and activation protoco
l and subsequent cyclization by solid-liquid phase transfer catalysis
under avoidance of high dilution conditions. (C) 1998 Elsevier Science
