  An efficient, sustainable, and regioselective one-pot synthesis of hitherto unreported 4-aroyl/hetaroyl/alkanoyl-5-alkyl/allyl/benzylsulfanyl-1,2,3-thiadiazoles has been achieved by [3 + 2] cycloaddition of α-enolicdithioesters with tosyl azide through cascade 1–2 (S–N) and 3–4 (C–N) bond connections involving Wolff-type heterocyclization. Optimally, the reactions are very fast and completed within 2–15 minutes, when a mixture of α-enolicdithioester and tosyl azide was stirred at 0 °C in the presence of Et3N under solvent-free conditions. Furthermore, no co-catalyst or activator is necessary. The eco-compatibility, mild conditions, excellent yields, easy purification, and avoidance of expensive/toxic reagents are advantages of this protocol to access this medicinally privileged substructure.

  通过 α 的 [3 + 2] 环加成，实现了迄今为止未报道的 4-芳酰基/杂酰基/烷酰基-5-烷基/烯丙基/苄基硫基-1,2,3-噻二唑的高效、可持续和区域选择性一锅法合成-烯醇二硫酯与甲苯磺酰叠氮通过级联 1–2 (S–N) 和 3–4 (C–N) 键连接，涉及 Wolff 型杂环化。最理想的是，当α-烯醇二硫酯和甲苯磺酰叠氮化物的混合物在无溶剂条件下、Et3N存在下于0℃搅拌时，反应非常快并在2-15分钟内完成。此外，不需要助催化剂或活化剂。生态相容性、温和的条件、优异的产量、易于纯化和避免昂贵/有毒试剂是该协议获得这种医学上特权子结构的优点。

  The synthesis of 3,4-dihydro-2H-1,3-thiazines from alpha-enolic dithioesters and 1,3,5-triazinanes has been achieved via a formal (3 + 3) annulation reaction under thermal conditions, where 1,3,5-triazinanes were utilized as three-atom synthons. This transformation is catalyst-free and additive-free.

  An operationally simple and facile synthesis of alpha-hydroxyimino-beta-oxodithioesters has been achieved by nitrosation of alpha-enolicdithioesters. They were further treated with internal alkynes to afford diverse 1,4-thiazin-3-ones via domino reduction/annulation strategy under mild reaction conditions. Importantly, this is the first straightforward entry to highly functionalized 1,4-thiazin-3-one derivatives from simple starting materials. (C) 2014 Elsevier Ltd. All rights reserved.
