Synthesis of 3-methyl-3-butenyl-1-pyrophosphate.
In an earlier communication (1) and in Paper I of this series (2) a 5 carbon intermediate in the biosynthesis of squalene from mevalonic acid has been described and identified as a-methyl3-butenyl-1-pyrophosphate (isopentenylpyrosphosphate). The compound has now been synthesized chemically both in unlabeled and in tritium-labeled form and it is shown to have properties identical with those of t...

متن کاملMethyl 4-hydroxy-3-(3'-methyl-2'-butenyl)benzoate, major insecticidal principle from Piper guanacastensis.
The CHCl3-soluble extract of Piper guanacastensis (Piperaceae) was found to have noteworthy insecticidal activity to Aedes atropalpus mosquito larvae (LC50 80.5 micrograms/mL). Bioassay-guided fractionation afforded methyl 4-hydroxy-3-(3'-methyl-2'-butenyl)benzoate (1) as the major bioactive constituent (LC50 20.5 micrograms/mL). The separation of compound 1 from its transesterification artifac...
متن کاملsynthesis of 3-aryl-2h-benzo[b]-1,4-oxazines in [omim]bf4 and reduction of organic compounds in methylimidazolium formate
در این پروژه ترکیبات 3-آریل-2h-بنزو[b]-4،1-اکسازین ها از مواد اولیه تجاری مشتقات دو آمینو فنول و ?-هالو کتون های آروماتیک در مایع یونی 1-اکتیل-3-متیل ایمیدازولیوم تترا فلورو بورات([omim]bf4) سنتز شده است. این واکنش توسط باز پتاسیم کربنات محلول از طریق o-آلکیلاسیون و سپس یک واکنش آمیداسیون درون مولکولی خود بخود در مدت زمان کوتاه انجام می شود. ترکیبات 4،1-بنزوکسازین به این روش با بهره خوب تا آلی ...
15 صفحه اولMethyl 2-(3-benzoylthioureido)acetate
In the title compound, C(11)H(12)N(2)O(3)S, the methyl acetate and benzoyl groups adopt a cis-trans configuration with respect to the thiono S atom across the C-N bonds. An intra-molecular N-H⋯O hydrogen bond is observed. In the crystal packing, mol-ecules are linked by inter-molecular N-H⋯S and C-H⋯O hydrogen bonds to form a two-dimensional network lying parallel to (101).
