[2] If two identical substituents are attached to an sp 3-hybridized atom, the descriptors pro-R and pro-S are used to distinguish between the two. Promoting the pro-R substituent to higher priority than the other identical substituent results in an R chirality center at the original sp 3-hybridized atom, and analogously for the pro-S substituent.

Enantioselective ketone reductions convert prochiral ketones into chiral, non-racemic alcohols and are used heavily for the synthesis of stereodefined alcohols. [1]Carbonyl reduction, the net addition of H 2 across a carbon-oxygen double bond, is an important way to prepare alcohols.
The first intended product was the Victa R-2, a four-seat single-engine light aircraft designed by Luigi Pellarini. [ 1 ] [ 2 ] [ 3 ] Pellarini's design was a low-winged, all metal tractor configuration monoplane with a T-tail , powered by a 180 hp (130 kW) Lycoming O-360 flat-four piston engine driving a constant-speed propeller .
The TR-2 has a cruise propeller and the trainer has a climb prop. Typically the TR-2 came with more navigation instruments and was better for cross country flying because of its speed and lower fuel consumption. The family also includes the Grumman American AA-1B Trainer and TR-2, plus the Gulfstream American AA-1C Lynx and T-Cat. [1]
