His father died when Bob was less than two years old, and his mother had to work hard to support her son. Boston, Massachusetts

His unusual talents were soon apparent to the MIT faculty, and his needs for individual study and intensive effort were met and encouraged. In just four years Woodward obtained both bachelor's and doctoral degrees. At that time he was only 20 years old of age. “Mind and Hand” 10 Harvard University Woodward joined the chemistry department at Harvard University, where he worked until his passed away in 1979.

The development of synthetic quinine is considered a milestone in organic chemistry although it has never been produced industrially as a substitute for natural occurring quinine.

Uskokovic实现，这被认为是第一个真正意义的奎宁合成。但是这一条合成路线的仍然没有实现对立体化学 的控制。完全立体选择的奎宁全合成直到2001年才由哥伦比亚大学的Gilbert Stork小组完成。这之后又有几 个选择性更好的合成路线被不同的小组报道。关于有机化学界这些合成的努力背后的动力，Gilbert Stork教 授的话给了最好的解释， 他说：“这些奎宁的全合成的价值其实和奎宁本身一点都关系没有。这就像数学家 们努力解决数学里的猜想一样：她推进了一个学科的发展
