Robust air-stable cyclometalated π-allyliridium C,O-benzoates modified by (S)-tol-BINAP catalyze the reaction of secondary aliphatic amines with racemic alkyl-substituted allylic acetates to furnish products of allylic amination with high levels of enantioselectivity. Complete branched regioselectivities were observed despite the formation of more highly substituted C-N bonds.
A convenient and versatile method for the preparation of α-hydroxymethyl ketone derivatives from the corresponding allyl silyl ethers or allyl carboxylates

experimental part, p. 896 - 914 (2009/12/06)
The ozonolysis of 1-substituted allyl silyl ethers or 1-substituted allyl carboxylates followed by treatment with bases gave the corresponding α-silyloxymethyl- or α-acyloxymethyl-ketones in good yields. It is proposed to proceed via the corresponding α-silyloxy- or α-acyloxyaldehydes intermediates followed by 1,4-group migration. The results of theoretical calculations are applicable to explain the experimental results.

Novel 8-aza-9-dioxothiaprostanoic acid compounds, their salts, and derivatives, are prepared from ethyl 7-(3-hydroxymethyl-2-isothiazolidinyl)-5-heptynoate S,S-dioxide by first hydrogenating the triple bond over a Lindlar catalyst, followed by mild oxidation, to produce the corresponding 3-formyl compound, which is condensed with the ylide prepared from dimethyl-(2-oxoheptyl)phosphonate to produce the α,β-unsaturated ketone, followed by reduction to the corresponding carbinol, and ester hydrolysis. The compounds are useful especially for the treatment of patients with poorly functioning kidneys, as hypotensives, or as platelet aggregation inhibitors.
