As for the second point, that of single authorship, multiple authorship would invariably have led to gaps and overlaps, thus making it difficult to assemble and assess recent research in a systematic and comprehens­ ive fashion.978-3-642-76840-8978-3-642-76838-5Series ISSN 0935-7092

For several decades organic synthesis has without doubt been the most spectacular branch of organic chemistry. While the late R.B. Woodwar

As long as the marine environment continues to be a source of biologically active substances and molecules of unprecedented architecture and complexity, it is anticipated that synthesis activity in this area will continue its remarkabl

Hydrolysis for 100 hours with sodium ethoxide in refluxing ethanol gives the free amine, which is converted to flustramine B by methylation. An overall yield of less than 0.5% is obtained over 9 steps.
