Abstract
Official abstract text for this publication.
The present invention provides (6Z,9Z)-6,9-dodecadien-1-yne of the following formula (1). Further, the present invention provides a process for preparing (6Z,9Z)-6,9-dodecadien-1-yne (1): the process comprising reacting a (3Z,6Z)-10-halo-3,6-decadiene compound of the following general formula (2), wherein X represents a halogen atom with a metal acetylide of the following general formula (3), wherein M represents Na, Li, K, Ag, Cu (I), MgZ, CaZ, or Cu(II)Z, wherein Z represents a halogen atom or an ethinyl group to form (6Z,9Z)-6,9-dodecadien-1-yne (1).
First claim
Opening claim text (preview).
The invention claimed is: 1. (6Z,9Z)-6,9-dodecadien-1-yne of the following formula (1): 2. A process for preparing (6Z,9Z)-6,9-dodecadien-1-yne of the following formula (1): the process comprising: reacting a (3Z,6Z)-10-halo-3,6-decadiene compound of the following general formula (2): wherein X represents a halogen atom with a metal acetylide of the following general formula (3): MC≡CH (3) wherein M represents Na, Li, K, Ag, Cu (I), MgZ, CaZ, or Cu(II)Z, wherein Z represents a halogen atom or an ethinyl group to form (6Z,9Z)-6,9-dodecadien-1-yne (1). 3. A process for preparing (8Z,11Z)-8,11-tetradecadien-3-yn-1-ol of the following formula (4): the process comprising: reacting (6Z,9Z)-6,9-dodecadien-1-yne (1) with a base; and subjecting a reaction mixture thus obtained to a homologation reaction with ethylene oxide to form (8Z,11Z)-8,11-tetradecadien-3-yn-1-ol (4). 4. A process for preparing (3E,8Z,11Z)-3,8,11-tetradecatrien-1-ol of the following formula (5): the process comprising: the process according to claim 3 for preparing (8Z,11Z)-8,11-tetradecadien-3-yn-1-ol (4); and subjecting (8Z,11Z)-8,11-tetradecadien-3-yn-1-ol (4) to a reduction reaction to form (3E,8Z,11Z)-3,8,11-tetradecatrien-1-ol (5), wherein the reduction reaction is carried out using (i) reduction with an organoaluminum compound, (ii) Birch reduction, (iii) ammonia-free Birch reduction, or (iv) Benkeser reduction. 5. A process for preparing (3E,8Z,11Z)-3,8,11-tetradecatrienyl acetate of the following formula (6): wherein Ac represents an acetyl group, the process comprising: the process according to claim 4 for preparing (3E,8Z,11Z)-3,8,11-tetradecatrien-1-ol (5); and acetylating (3E,8Z,11Z)-3,8,11-tetradecatrien-1-ol (5) to form (3E,8Z,11Z)-3,8,11-tetradecatrienyl acetate (6).
