Abstract
1,3,2-Diazaphospholenes (DAPs) are an emerging class of organic hydrides. In this work, we exploited them as efficient catalysts for very mild reductive Claisen rearrangements. The method is tolerant towards a wide variety of functional groups and operates at ambient temperature. Besides being enantiospecific for substrates with existing stereogenic centers, the diastereoselectivity can be switched by varying solvents and DAP catalysts. The reaction kinetics show direct rearrangements of O-bound phospholene enolates and provide a proof-of-principle for catalytic enantioselective reactions.

Abstract
Hydrostannations of propargylic glycine esters with the new hydrostannation catalyst [Mo(CO)3(CNtBu)3] (MoBI3) gave rise to alpha-stannylated allylic esters in good yield and with high regioselectivity. The chelate Claisen rearrangements of these esters allow the syntheses of gamma,delta-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.

Abstract
Ester enolate Claisen rearrangement of highly substituted amino acid allylic esters 4 allows for the synthesis of sterically demanding amino acids 5 with beta-quaternary carbon centers. Because of enolate fixation by chelation, the rearrangement occurs in a highly diastereoselective fashion. The methodology is suitable not only for glycine derivatives but also for allylic esters of various amino acids. In this case amino acids with two vicinal quaternary carbon centers are created. With unsymmetrically substituted allylic esters like 4k-n the rearrangement proceeds with a high degree of diastereoselectivity.
