Abstract
We have developed a simple methodology to transform cis-syn-cis-triquinane derivative 2 into the diindole based macrocycle 6 involving Fischer indolization and ring-closing metathesis (RCM). Various spiro-polyquinane derivatives have been assembled via RCM as a key step.

Abstract
A series of oxazolidin-2-one-4-carboxylic amide compounds (1a-f) were designed and synthesized as the non-phosphate S1P(1) receptor agonists. The single crystal of 1e was prepared and solved to elucidate the structure of 1a-f. EC(50) of 1a-d were about 1.1-3.6 μM in S1P(1) Redistribution® assay, and their cytotoxicity was 8-40-fold lower than FTY720. Though its S1P(1) agonist activities in vitro were about 1000-folds weaker than (S)-FTY720-P, at a dose of 10mg/Kg, the immunosuppressive effects of 1a were comparable to FTY720. So oxazolidin-2-one-4-carboxylic amide derivatives were found as potential immunomodulator, compound 1a could be considered as a lead compound, rational modifications of 1a are anticipated using medicinal chemistry techniques and molecular modeling to obtain analogs with higher affinity and better clinical therapeutic properties.

Abstract
A highly diastereoselective domino reaction of 2,6-diaminopyrimidine-4-one with structurally diverse aryl aldehydes and various barbituric acids in water under microwave irradiation is described. The products are 6-spiro-substituted pyrido[2,3-d]pyrimidines with high diastereoselectivities (up to 99: 1) in which the major diastereomer bears a cis relationship between substituents at the 5- and 7-positions. Furthermore, the mechanism for diastereoselectivity was confirmed by DFT (B3LYP) calculations.

Abstract
This article brings together for the first time reviews of all the synthetic attempts towards the spirocyclic histrionicotoxin alkaloids published since the discovery of the group in 1971. This covers 5 total syntheses of the fully unsaturated parent alkaloid HTX-283A, 7 total syntheses of perhydrohistrionicotoxin, 15 total syntheses of other members of this alkaloid family, 25 formal syntheses, and 19 partial syntheses involving the successful formation of the core azaspirocyclic structure but lacking advancement towards the target structure.

Abstract
[reaction: see text] The preparation of phosphorus-containing trienes featuring two diastereotopic vinyl moieties followed by a diastereoselective ring-closing metathesis is described. This methodology allowed for the synthesis of novel highly functionalized P-stereogenic heterocycles featuring both an exo- and an endocyclic double bond. An investigation into the factors influencing the diastereochemical outcome of the ring-closing metathesis is also presented, revealing that the geometry of the double bonds conjugated to phosphorus is important and that 1,3-stereoinduction is superior to 1,4-stereoinduction for these reactions.

Abstract
Highly functionalized spirocyclic pyrans can be obtained through the Achmatowicz rearrangement of furyl carbinols by taking advantage of the different rates of reaction for epoxidation and nucleophilic addition. Through this methodology, spirocyclic units of various ring sizes can be selectively generated with complete stereocontrol.
