SELECTIVE CYCLIZATION OF 2-PROPARGYLTHIO-6-METHYL-PYRIMIDIN- 4(1 H)-ONE TO THIAZOLO [3,2-a] PYRIMIDIN 7-ONE
Selective transformation of 2-propargylthio-6-methyl-pyrimidin-4(1H)On e (2) to 3,5-dimethyl-7H-thiazolo [3,2-a] pyrimidin-7-one (3) is performed under the conditionof base catalysis . For elucidation of structure, palladium catalyzed cyclization reaction of (2) was carried out and the structures of the products were assigned (5) and (6). These compounds underwent isomerization to (3) and (4...

In the title mol-ecule, C(16)H(19)BrO(3), all non-H atoms apart from the Br atom are approximately coplanar, with a maximum deviation of 0.242 (4) Å. The C-C-C-Br torsion angle is 66.5 (4)°.
متن کاملPhotochemical Rearrangement of 8- methyl Spiro [2.5] oct-7-en-4-one to 4-methyl Spiro [2.5] oct-4-en-6-one
Irradiation of &methyl spiro [2.5] oct-7-en-4-one through its singlet excited state resulted in the formation of 4-methyl spirO [2.5] oct-4-en -6-one. We have used the cyclopropyl moiety in the molecule as a probe to study the operating mechanism in the photochemistry of ?, ?-unsaturated compounds. The results showed that this photoisomerization probably occurs through a concerted process.

در این تحقیق، ابتدا از واکنش 5-برمو-2-کلرو-6- متیل-4-پیریمیدین آمین (1) با هیدرازین هیدرات در حلال اتانول، 5-برومو-2-هیدرازینو -6-متیل -4-پیریمیدین آمین (2) به دست آمد. سپس از واکنش این ترکیب با تری اتیل اورتو استر های مختلف در حلال استیک اسید محصولات تری آزولوپیریمیدین (a,b3) حاصل گردید. همچنین از واکنش مشتق هیدرازین دار (2) با سدیم نیتریت در حلال استیک اسید و آب حد واسطی ایجاد شده است که از ر...

interesting results because of the regular arrangement of the molecules in the environment.1–3 We previously reported on the photocycloaddition reaction of 4-methoxy-6-methyl-2-pyrone (1a) (Fig. 1) with maleimide (2) in the solid state to give a highly stereoselective [2 + 2] cycloadduct4 owing to the formation of two sets of 1:1 complex crystals between (1a) and (2) (Fig. 1).5 The crystal show...
