Pheromone synthesis. Part 253: Synthesis of the racemates and enantiomers of triglycerides of male Drosophila fruit flies with special emphasis on the preparation of enantiomerically pure 1-monoglycerides
TL;DR: The racemates and enantiomers of triglycerides 1a–e (2,3-ditigloyloxypropyl esters of palmitic, palmitoleic, stearic, oleic, and linoleic acids) of male Drosophila fruit flies were synthesized in three steps via 1-monoglycerides 4a-e derived from the above fatty acids.

The Stereoselective Acylation of Racemic Secondary Alcohols with Phenyltrifluoromethylketene as an Experimental Test of the Stereochemical Analogy Model
Ernst Anders,Ernst Ruch,Ivar Ugi +2 more
TL;DR: In this article, the stereochemical analogy model for stereoselective reactions was tested on acylations of racemic chiral secondary alcohols with phenyltrifluoromethylketene.

Photochemical Reaction between Tertiary Allylic Amines and Chromium Carbene Complexes: Synthesis of Lactams via a Zwitterion Aza Cope Rearrangement.
TL;DR: Photolysis of chromium carbene complexes in the presence of tertiary allylic amines resulted in a zwitterionic aza Cope rearrangement to produce unsaturated lactams in fair yield.

Asymmetric pinacol-type rearrangement of α-hydroxy methanesulfonates promoted by triethylaluminum — preparation of optically pure α-aryl and α-vinyl ketones —
TL;DR: Asymmetric pinacol-type rearrangement of aryl or vinyl group in α-hydroxy methanesulfonates is promoted by Et3Al in CH2Cl2 at −78°C to afford optically pure α-aryl or α-vinyl ketones as mentioned in this paper.
