Mo(CO)3(CNt-Bu)3 (MoBI3) was found to be a suitable catalyst for the regioselective hydrostannation of several types of alkynes, especially propargyl alcohol derivatives, affording preferentially the α-stannylated products

Application of the molybdenum catalysed hydrostannation towards propargylic esters of amino acids allows for the regioselective synthesis of α-stannylated allylic esters, suitable substrates for chelate Claisen rearrangements, α-Stannylated allylic carbonates can be subjected to palladium catalysed allylic alkylations using chelated amino acid ester enolates as nucleophiles. The stannylated amino acids obtained can be further modified via crosscoupling reactions.

Hydrostannations of propargylic glycine esters with the new hydrostannation catalyst [Mo(CO)3(CNtBu)3] (MoBI3) gave rise to α-stannylated allylic esters in good yield and with high regioselectivity. The chelate Claisen rearrangements of these esters allow the syntheses of γ,δ-unsaturated amino acids with a vinylstannane moiety in the side chain. The amino acids obtained can be further modified by cross-coupling with various types of electrophiles.
