European grapes

Including European grape moth (Eupoecilla ambiguella,Z9-l2 OAc + 12 OAc). 

Hydroboration/protonolysis of ( )-enynes completes a route to (E, Z)-dienes. For example, the ( )-enyne generated in Figure B4.6 was converted into (IE, 9Z)-7,9-dodecadien-l-yl acetate (a natural sex pheromone of the European grape vine moth Lobesia botrana) by hydroboration with Sia2BH followed by acetic acid protonolysis (Equation B4.7). 

Many insect pheromones have conjugated cis, trans-diene system l52, l53). The versatility of these reactions is exemplified in the synthesis of many natural products l53-154, 55 In Eq. 99, the four step synthesis of a natural sex pheromone of the European grape vine moth (Lobesia botrana), (7E, 9Z)-7,9-dodecadien-l-yl acetate, is illustrated 155).

There are 4 main types of grapes grown in North America European, or wine grapes (Vitis vinifera) American (V. labrusca), such as Concord hybrids between European and American and muscadine (V. mtundifolia). European grapes generally are most susceptible to diseases. American grapes are the most cold-hardy. Their hardiness (Zones 4-10) depends on the species and cultivar. 

Many attempts were also made in Eastern states to establish vineyards and to found an Eastern wine industry, procedure being much along the same lines as those tried successfully in California. Unfortunately, European grapes will not flourish in these sections of the United States and all such attempts ended in disaster. About the middle of the last century Nicholas Long-worth, Sr., experimented with the native Catawba grape in Ohio... 

Negishi and Abramovitch have described an extremely elegant use of two generations of Brown chemistry in the four-step synthesis of the insect sex pheromone of the European grape vine moth Lobesia botrana, (7E,9Z)-dodeca-7,9-dien-l-yl acetate (101). The now familiar acetylene zipper reaction converts (102) into (103), the terminal acetylene (103) produced being then coupled via the borane (104) to give the ( )-dodec-7-en-9-yn-l-yl acetate (105) in >99% isomeric purity and in 70% yield. Hydroboration then leads to the desired product (Scheme 26). 

Coupling of EAD to GC was first achieved in 1969, and further developed in 1975 in studies on the sex pheromone of the European grape vine moth. The use of capillary columns allowed a continuous stream of the GC effluent on to the antenna, which had previously not been possible. The GC effluent can be split between the EAD and an EID allowing the correlation of biological response to identified compounds (Figure 12). Recent studies on the Egyptian armyworm found that the use of the whole insect provides better results than the use of the excised head, or the antenna, and showed that as little as 15 pg of compound could be detected. 

Wines— Varieties of the European grape are ideal for alcoholic fermentation. They contain 18 to 24% sugar with only 0.5 to 1.5% acidity. Worldwide, more than 85% of the grape crop is used for wine production.

The failure in growing European grapes in the New World is not restricted to colonial Brazil, as it has also been recorded in the history of North American agriculture. 

European bunch grapes were first introduced into Florida by early European settlers, but they failed to flourish due to disease and poor tolerance to the climate (Lane, 1997). A second attempt using V. labrusca L. also met with failure. Other early efforts to grow European grapes, including several attempts by Thomas Jefferson, the third President...
