How To Play

PREPARATION:

Place the game board on a flat surface with enough room around the game board for placement of the draw deck of cards, marker chips and discards for each player.

For 2 players or 2 teams: Team players must be evenly divided into two teams. Team members must alternate their physical positions with opponents around the playing surface.

For 3 players or 3 teams: Team players must divide evenly into three teams. Team members must alternate their physical positions every third player around the playing surface.

Players cut cards and lowest card deals - Aces are high. The dealer should shuffle the cards and deal out the same number of cards to each player (see table below for proper number of cards to be dealt). Be sure all members of a team use the same color marker chips.

RULES:

Set-up

Beginning with the player to the left of the dealer and moving in a clockwise direction, each player selects a card of their choice from their hand and places it face up on a discard pile (players should start their own discard pile in front of them visible to all other players) and then places one of their marker chips on the matching card on the game board. Each card is pictured twice on the game board. Jacks do not appear on the game board. A player can play on either one of the card spaces as long as it is not already covered by another marker chip. Once a marker chip has been played, it cannot be removed by an opponent except when using a one-eyed Jack as explained below.

The Jacks

There are 8 Jacks in the card deck. The 4 Jacks with TWO EYES are wild. To play a two-eyed Jack, place it on your discard pile and place one of your marker chips on any open space on the game board. The 4 jacks with ONE EYE are anti-wild. To play a one-eyed Jack, place it on your discard pile and remove one marker chip from the game board belonging to your opponent. That completes your turn. You cannot place one of your marker chips on that same space during this turn. You cannot remove a marker chip that is already part of a completed SEQUENCE. Once a SEQUENCE is achieved by a player or a team, it cannot be broken. You may play either one of the Jacks whenever they work best for your strategy, during your turn.

Experimental

Experiment
2.7 g (12.3mmol) of a solution of 7  was combined with 41 mL of 1,2-dichloroethane, 4.3 mL (36.9 mmol) of 2,6-lutidine, and 4.4 mL (24.6 mmol) of trimethylsilyl trifluoromethanesulfonate (TMSOTf) at room temperature. After being stirred at 45 ºC for 1.5 h, the mixture was cooled to 0 ºC, and 7.4 mL of hydrogen fluoride-pyridine complex was added. After being stirred for 15 min, an aqueous solution of NaHCO₃ was carefully added. The mixture was separated, and the aqueous layer was extracted with ether. The combined organic layer was washed with brine, dried over MgSO₄, and concentrated under reduced pressure. Purification by column chromatography (EtOAc/hexane 1:1) resulted in 2.61 g (11.9 mmol) of hydroxy ketone 8 as a white solid.

Breakdown of Procedure/ Notes on Procedure

  1. Combine
    • 2.7 grams of 7
    • 41 mL of 1,2-dichloroethane
    • 4.3 mL of 2,6-lutidine
    • 4.4 mL of trimethylsilyl triflouromethanesulfonate (TMSOTf)

    2. Combine

  2. Stir and heat at 45°C for 1.5 hours.
    Heat
  3. Cool to 0°C and add 7.4 mL of hydrogen flouride-pyridine complex.
      Ice
  4. Stir for 15 minutes and add an aqueous solution of NaHCO3.
    Stir
  5. Use a separation funnel to extract the aqueous layer (bottom layer) with ether.
    SepFunnel
  6. Use a separation funnel to wash the aqueous layer with brine (bottom layer), then add MgSO4 and use gravity filtration to obtain filtrate, which should then be concentrated under reduced pressure.
    Chemicals
  7. Obtain the desired compound 8, through column chromatography, with a developing solvent of 1:1 Ethyl Acetate and Hexane.
    Column
  8. This should result in 2.61 grams of a white solid that should be hydroxy ketone.
