Fetal Reactions
By the use of ultrasound, chemical analysis and histologic techniques, the knowledge of embryo and fetal growth and developments is increasing steadily. It has been demonstrated that the fetus can respond to sound, bright light and touch. Accordingly, works on fetal responses to external stimuli during the third trimester may ultimately lead to improvements in the techniques of antepartum fe...

متن کاملREACTIONS OF DIHYDROPYRIDINES WITH BENZYNE
Reactions of 1 ,Zdihydropyridines (la-c) and 1,4-dihydropyridines (2a-c) in the presence of benzyne (3) under thermal conditions, and in the case of (2c) under photochemical conditions, have been investigated. Benzyne acts as an oxidizing agent to convert dihydropyridine (la) and (2a) to the corresponding pyridine (4) or adds as a dienophile to (lb-c).
متن کاملSynthesis of 1,4-Phenanthrenequinones via Stannic Chloride-Induced Cyclizations.
Substituted 1,4-phenanthrenequinones such as 1 are useful building blocks for the preparation of novel materials. Katz and others have shown that compounds such as 1 can be transformed into helicenes by DielsAlder reactions.1 Certain 1,4-phenanthrenequinones also have potential as synthetic intermediates for natural products synthesis. Additionally, some naturally occurring 1,4-phenanthrenequin...
متن کاملCarbocations as Lewis Acid Catalysts: Reactivity and Scope
One potential Lewis acid that has received negligible attention as a catalyst is the carbocation. Here we show the potential of triaryl methylium ions as highly powerful Lewis acid catalysts for organic reactions. The Lewis acidity of the triaryl methylium ion can be easily tuned by variation of the electronic properties of the aromatic rings and the catalytic activity of the carbocation is sho...
