論文句子2

Question 1

Up to the time of their receipt of the Nobel Prize in 1950 it seems that, for the most part, the synthetic community heeded the demand of Diels and Alder, as their cycloaddition reaction did not feature prominently in any total synthesis prior to the stereocontrolled generation of cantharidin by Stork et al. in 1951, or the first synthesis of morphine reported a few months later in which Gates and Tschudi employed the pericyclic process.

Answer 1

up to the time of: 直到
it:虛主詞
prior to + something 在…之前 （放在名詞之前）
as:因為

Question 2

First, with few exceptions, total synthesis during that period played a role inclined more towards structure verification than as its own unique vehicle to advance the field of organic synthesis, as it is practiced today.

Answer 2

with few exceptions : 除了少數的例外
more than : 後面放形容詞有非常的意思，但這裡不是，這裡是(更….. 而不是…..、比 …. 更….)的意思
as: 1作為(介係詞)2像…一樣(連接詞)

Question 3

As such, in a discipline defined by converting known materials by existing methods into other compounds, practitioners would not likely have regarded being the “first ”to employ a particular transformation in a synthesis as an important contribution, and the number of compounds in which the Diels ± Alder reaction had been demonstrated was limiting in terms of potential synthetic targets.

Answer 3

As such: 就其真正的意義來說
by :1藉由2 透過某個方法，也可以不用於被動
in terms of : 從…角度而言
