A manganese‐catalyzed C−H annulation of ketimines with poly‐substituted ester‐activated allenes toward the synthesis of 1‐aminoindanes bearing two vicinal all‐substituted carbon stereocenters and an exocyclic double bond was developed. The reaction features high diastereoselectivity, high E/Z selectivity, 100% atom‐economy, broad substrate scope and good functional group tolerance.

The first stereoselective total synthesis of the marine-derived antimicrobial amino-alcohols, crucigasterins A, B and D has been accomplished through a commonintermediate starting from pent-3-en-1-ol. The method involves the Sharpless asymmetric aminohydroxylation and Julia and Wittig olefinations as the key steps.

Metal‐free selectivity: The first metal‐free one‐pot three‐component highly chemo‐ and regioselective catalytic synthesis of homoallylboranes using simple N‐heterocyclic carbenes (NHC) and amines is presented. The catalytic reaction between B2(pin)2, α,β‐unsaturated aldehydes and 2‐(triphenylphosphoranylidene)acetate esters proceeds through a catalytic metal‐free β‐boration/Wittig cascade sequence

Nucleophilic phosphanylation of ortho-fluorophenylacetic acid or ortho-fluorobenzylamine with PhPH2 using KOtBu as the base affords the hydrophilic tertiary phosphanes 3 and 4a with terminal CH2-COOH and CH2-NH2 substituents. The corresponding secondary phosphane ligands 2 or 5 may be obtained by Pd-catalyzed P-C coupling of ortho-iodophenylacetic acid with PhPH2 or selective nucleophilic phosphanylation
