Abstract
Active Sn(0) particles are synthesized in high yields by the chemical reduction of the blue–black stannous oxide using freshly prepared sodium stannite solution as reducing agent at 40 °C and 60 °C. The Sn(0) particles are characterized using powder XRD, SEM, and DSC. The as-synthesized Sn(0) particles are applied as reagent for the regioselective synthesis of homopropargyl alcohols from propargyl bromide and aldehydes in distilled water at room temperature (in 50%–84% yields). No assistance of heat, microwave, ultrasound, organic co-solvent, co-reagent, or inert atmosphere is required for this reaction. The propargylation reaction is highly chemoselective towards aldehyde over other less electrophilic carbonyl functional groups such as ketone, amide, and carboxylic acid. Our in-house synthesized homopropargyl alcohols can be used to synthesize conjugated 1,3-diynes.

Abstract
Tiacumicin B is an antibiotic endowed with the remarkable ability to interact with a new biological target, giving it an inestimable potential in the context of the ever-growing and worrisome appearance of resistances of bacteria and mycobacteria to antibiotics. The synthesis of an aglycone of tiacumicin B ready for glycosylation is reported. The key steps of this approach are a [2,3]-Wittig rearrangement, a Pd/Cu-catalyzed allene-alkyne cross-coupling, a E-selective cross-metathesis, and a final ring-size selective macrolactonization.

Abstract
An efficient method for the allylation of aldehydes containing a broad range of functional groups using potassium allyltrifluoroborate is described. The reaction utilizes a catalytic amount of 18-C-6 in biphasic media under open atmosphere and room temperature to provide the corresponding homoallylic alcohols in high yields and without the necessity of any subsequent purification.
