摘要:
A PROCESS FOR THE PREPARATION OF CIS-B-BERGAMOTENE INVOLVING A NOVEL CYCLIZATION REACTION IS DISCLOSED. THE NOVEL CYCLIZATION REACTION CAN BE USED TO FORM NOVEL OXATRICYCLO(5.2.0.04,9) NONYL COMPOUNDS. CIS-B-BERGAMOTENE AND THE NOVEL OXATRICYCLO(5.2.2.04,9) NONYL COMPOUNDS ARE USEFUL AS PERFUMES.
摘要:
Organic compounds of the class vinyl substituted phthalans are preared chemically from the corresponding vinyl isobenzofurylium compounds. The novel compounds are useful for their antidepressant activity.

A METHOD OF ISOLATING GIBBERELINS FROM CULTURE FLUID OBTAINED BY CULTIVATING AN ORGANISM, E.G., THE FUNGUS FUSARIUM MONILIFORME SHELD., WHICH COMPRISES PRECIPITATION OF GIBBERELLINS WITH IRON SALTS AT A PH OF 2.5-4.5 WITH SUBSEQUENT SEPARATION OF THE PRECIPITATE AND DRYING.
摘要:
In the synthesis of prostaglandins of the ''''one''''-series an alteration in the conventional reaction sequence avoids side reactions and provides an improved synthesis via a series of novel intermediates. In this improved synthesis the side chain at the 8 position is attached to the five membered ring before the side chain at the 12 position is attached.
